At the beginning of April, the US research laboratory Fermilab published a new result for the magnetic dipole moment of the muon. The result caused a broad media response because it deviates from the theoretical predictions and thus questions the previous understanding of the laws of nature. Researchers from the Albert Einstein Center for Fundamental Physics (AEC) at the University of Bern were involved in the theoretical predictions. Prof. Martin Hoferichter, theoretical physicist at the AEC, explains the background.
Image: M. HoferichterIn Italy, female high school graduates choose to study physics much more naturally than it has been the case in Switzerland so far. Ilaria Zardo was one of these young Italian women who first became enthusiastic about studying physics and later about academic research. Today, as a professor at the University of Basel, she and her research group study heat flows at the nanoscale level.
When people talk about CERN, they inevitably think of the large-scale experiments at the Large Hadron Collider (LHC). But the European Laboratory for Particle Physics has even more to offer: A small but powerful experiment called FASER is currently being assembled at CERN, involving research teams led by Geneva physics professors Anna Sfyrla and Giuseppe Iacobucci and by Bern physics professor Akitaka Ariga. FASER proves: Even comparatively inexpensive experiments have the potential for groundbreaking scientific findings.
Almost ten years ago, the European Laboratory for Particle Physics (CERN) made headlines with the discovery of the Higgs particle. These days, the LHCb experiment at CERN has published results that also have the makings of a real scientific sensation: studies of the so-called beauty quark suggest that there could be a fifth, super-weak force in addition to the four known forces of nature (electromagnetism, gravitation, strong and weak interaction). However, CERN researchers still have a lot of work ahead of them to confirm this spectacular hypothesis. At the forefront: particle physicists from the University of Zurich and EPF Lausanne

Until his retirement in 2017, Martin Pohl was a physics professor at the University of Geneva and worked on particle physics research projects for almost half a century. Drawing on this wealth of experience, a book has been written in which Pohl knowledgeably traces the developmental strands of this fundamental discipline. The culmination is the 'Standard Model' of particle physics - for Pohl a scientific highlight and a burden at the same time.
This community roadmap summarizes a survey of the Swiss large-scale infrastructure requirements in the broad field of photon science for the years 2025–2028, drawing from the current situation both in Switzerland and abroad.

Ein Vortrag von Prof. Dr. Thomas Stocker, Physikalisches Institut, Universität Bern
In the laboratories of modern physics the elementary components of matter are studied. To do this, scientists sometimes build artificial atoms to help them understand the laws of matter. A research team at the Paul Scherrer Institute (Villigen/AG) uses a specifically modified helium atom to determine the exact mass and other properties of pions. Pions could help to understand more precisely where atomic nuclei get their mass from.

Claudia Merlassino was born in Genoa, studied physics in Milan and completed her doctorate at the University of Bern in October 2019, since then she has been doing research at Oxford University in the UK. At the age of 28, the Italian experimental physicist has already made a remarkable journey as a researcher. She is now receiving the PhD prize in Swiss particle physics - among other things for her findings in the context of the most massive of all elementary particles.
Executive summary of an analysis prepared by the Centre for Economics and Business Research (Cebr) for the European Physical Society (EPS)
On June 19th CERN Council adopted the update of the "European Strategy for Particle Physics 2020". This document updates an earlier strategy paper that was adopted by the Council in 2013, just after the Higgs discovery in 2012. It identifies the medium and long-term priorities of fundamental research in particle physics and thus forms an important basis for the construction of the European research infrastructure. The implications of this strategy update for Swiss particle physics are answered by Rainer Wallny, Professor of Particle Physics at ETH Zurich and President of the Swiss Institute of Particle Physics (CHIPP), the umbrella organisation of Swiss particle physics.
The delta+ is a type of baryon, the family of sub-atomic particles to which the more well-known proton and neutron belong. A team of physics enthusiasts at the International School of Geneva is working intensively on these extremely unstable elementary particles. In September they will travel to Hamburg for an experiment at the renowned particle physics research institute DESY. They owe this extraordinary research trip to winning this year's “Beamline for Schools” (BL4S) competition at CERN.

When analyzing data from the XENON1T detector for dark matter, a signal excess was observed. The UZH researchers do not yet know for sure where this unexpected signal comes from. They say the origins could be relatively banal, but they could also indicate the existence of new particles or hitherto unknown properties of neutrinos.
To recognise the International Day of Light 2020 and the 60th anniversary of the laser, the Swiss Physical Society (SPS) publishes a detailed report by René Salathé (EPFL) to record the development and milestones in laser science from 1960 to 1980 in Switzerland.

A team of researchers led by ETH Professor Günther Dissertori is working on a new generation of PET scanners that could in future be of great use in pharmacological research and in the treatment of Alzheimer's patients. The technical innovation is based, among other things, on fundamental research at CERN.
FCC - these three letters stand for the vision of a new ring accelerator that could be built at the European particle physics laboratory CERN in Geneva. With this long-term goal in mind, Swiss physicists founded the CHART research initiative five years ago. Now the demonstrator of a powerful magnet is available. If the tests are successful, a very first step towards decisive progress in infrastructure for basic research, but also in applications such as, e.g., innovative instrumentation for medical therapies will be achieved.
The T2K Collaboration has published new results showing the strongest constraint yet on the parameter that governs the breaking of the symmetry between matter and antimatter in neutrino oscillations.
Scientists at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) have spent around ten years building the Spectrometer / Telescope for Imaging X-rays (STIX). Since 10 February, the research instrument is travelling to the Sun. It will provide accurate measurements of the solar atmosphere and the solar wind and will also cover the polar regions of the Sun that cannot be observed from Earth.
With its European particle physics laboratory CERN, Geneva attracts many researchers to Switzerland. This was also the case with François Drielsma (28). In a doctoral thesis supervised by Prof. Alain Blondel (University of Geneva), the Belgian-born scientist investigated a completely new way to build a particle accelerator.
Particle physicists from all over Europe are currently discussing the future of European particle physics, when the current ring accelerator LHC will be decommissioned around 2035. Next May, the decision could be taken launch technical and financial feasibility studies for the construction of a new, even more powerful particle accelerator.
This week’s drafting session marks final discussions for the update of the European strategy for particle physics
Elementary particle physics and the large-scale CERN research facility have repeatedly inspired artists to engage with modern scientific research. The latest example is the movie 'Les Particules' by French-Swiss filmmaker Blaise Harrison (39). In this art piece scientific research serves as an escape and dream world for an adolescent.
Lesya Shchutska (pronounced: Schutska) is 33 years old and already Professor of Elementary Particle Physics at the Swiss Federal Institute of Technology Lausanne (EPFL). "At the moment I can't imagine doing anything other than physics," says the researcher, who deals with particles that so far only exist in the minds of theoretical physicists.
At the occasion of the Swiss Geoscience meeting in Fribourg in November 2019, the ACP Award for Atmospheric Research was presented to Daniele Nerini for his PhD thesis “Ensemble precipitation nowcasting: limits to prediction, localization and seamless blending”.

In deep underground tunnels of former mines near the Japanese Alps, teams of scientists with Swiss participation are researching various types of elementary particles. Over the next few years, powerful research instruments will be put into operation with which scientists want to discover the nature of neutrinos. The hoped-for results could lead to solving of deep puzzles in our understanding of the universe.
Hardly any elementary particle occurs more frequently in the universe than the elusive neutrino. The investigation of the almost massless tiny particle is a focus of current elementary particle physics. Perhaps the most important contribution to the understanding of neutrino has been made over twenty years by the Japanese Super-Kamiokande detector, in which several Swiss research groups are involved. A visit to the Japanese mountains.
Pickel, Schaufel und Spatel gehören zwar noch immer zur archäologischen Feldausrüstung, immer öfter kommen aber bereits im Feld oder spätestens bei der Auswertung im Büro High-Tech Geräte zum Einsatz. Tragbare Röntgenfluoreszenz-Analysatoren sind ein Beispiel solcher Geräte, die zur grossen Freude archäologischer Konservatoren zerstörungsfreie Analysen ermöglichen.
Graben oder nicht graben? Das ist oft die Frage! Die Entscheidung müssen Archäologen aber nicht dem Zufall überlassen. Geophysikalische Prospektionen und die Fernerkundung erlauben sehr weit gehende Einsichten in den Untergrund, bevor die erste Schaufel Erdreich bewegt wird. Die dadurch gewonnenen digitalen Daten bilden die ideale Grundlage, um einen antiken Fundort durch gezieltes Anlegen von Grabungsschnitten möglichst detailliert zu erkunden.
Wollen Archäologen ohne zu graben den Untergrund erforschen, dann greifen sie zu geophysikalischen Methoden. Bei Luftbildauswertungen und elektrischen Widerstandsmessungen in Studen kam Erstaunliches zu Tage – aber auch die Erkenntnis, dass ein Grossteil des römischen Vicus undokumentiert dem Kiesabbau zum Opfer gefallen ist.
Neutrinos are ubiquitous yet elusive particles that could shed light on the early evolution of the universe. As one of the world’s major laboratories for neutrino physics, Fermilab partners with leading organizations around the globe to get a firmer grasp on these subtle particles.
The two researchers from the Astronomical Observatory of the University of Geneva share this extraordinary distinction with James Peebles, Professor Emeritus at Princeton University in the United States.

A labyrinth of mirrors, a shiny pot, countless cables and digital displays. Visiting Matteo Fadel at his workplace at the University of Basel, he first takes us to the laboratory where he tracks strange quantum phenomena. Somewhere in the midst of all this apparatus, several hundred atoms are trapped and brought into a state that still causes physicists a lot of headaches today.
Controlling the amount of phosphate in cells, the processes involved in catalysts, land use in Madagascar and a paradox of quantum physics – these are the topics for which the Swiss Academy of Sciences (SCNAT) has awarded the Prix Schläfli 2019 to the four most important insights gained by young researchers at Swiss universities. Murielle Delley (Chemistry), Matteo Fadel (Physics), Rebekka Wild (Biology) and Julie Zähringer (Geosciences) receive the prize for the findings arrived at in their dissertations. For the first time, six of the candidates for the Prix Schläfli in Physics were also selected to participate in the Lindau Nobel Laureate Meeting.
Radioactive waste from nuclear power plants can take a long time to decay. For plutonium-239 the half-life - that is the time until half of the atoms of a sample have decayed - is no less than 24,000 years. But this is nothing compared to the half-life of the noble gas xenon-124, as an international research team with collaborators from the University of Zurich has now shown.
From 2026, the performance of the large-scale experiments at the European particle physics laboratory, CERN, in Geneva will be significantly increased. The preliminary work for the upgrade of the large particle accelerator LHC and the associated detectors is currently in full swing. An important contribution is made by the University of Bern, where doctoral student Armin Fehr (26) and his colleagues are working on a component for the ATLAS detector. This component will enable the read-out of the greatly increased data rates from 2026 onwards.

CERN in Geneva is the leading particle physics laboratory worldwide. Large particle accelerators based on the most innovative technologies are used there for fundamental research. One year ago, the innovation park “PARK INNOVAARE” in Villigen (AG) launched, together with CERN, the BIC of CERN program: it supports start-ups and high-tech micro-companies using CERN technologies for commercial applications. These days the second call for proposals has started.
The Swiss Academies of Arts and Sciences have been requested by the Confederation to prepare roadmaps for research infrastructures for the various scientific fields. These roadmaps will provide a basis for decision-making on the allocation of federal funding for costly research facilities over the period 2025–2028. SCNAT is responsible for implementing this new procedure within the Swiss Academies, and Secretary General Jürg Pfister believes that it offers the scientific community an opportunity for wider involvement.
The LHCb collaboration at CERN has seen, for the first time, the matter–antimatter asymmetry known as CP violation in a so-called D0 meson. LHCb is one of the four large experiments performed at the Large Hadron Collider (LHC) with Swiss participation of Ecole polytechnique fédérale de Lausanne (EPFL) and University of Zurich.
Fünf junge Schweizer haben sich für die Internationale Physik-Olympiade vom 7. bis 15. Juli in Tel Aviv, Israel qualifiziert. Sie gewannen Gold an der 23. Schweizer Physik-Olympiade 2019.
Gravity accompanies us in our everyday lives—from early morning, when we get out of bed, to late evening, when we drop tiredly onto the mattress. Although no other force of nature shapes our lives as much as gravity, we still know little about it. Many scientists around the world are working to uncover the secrets of gravity. One of them is researching in Canton Aargau: the 32-year-old particle physicist Anna Soter.
The CHIPP Prize is to reward annually the best PhD student in Experimental or Theoretical Particle Physics. In the evaluation, emphasis will be given to the quality of PhD scientific work and to its relevance within the student's research group, as well as to novel ideas brought up by the candidate.
The Periodic Table of Chemical Elements is one of the most significant achievements in science, capturing the essence not only of chemistry, but also of physics and biology. 1869 is considered as the year of formulation of the modern concept of the Periodic System by Dmitri Mendeleev (and others). 2019 is the 150th anniversary of this formulation and has therefore been proclaimed the "International Year of the Periodic Table of Chemical Elements (IYPT2019)" by the United Nations General Assembly and UNESCO.

In the first workshop in April, the status of the field was reviewed and discussed. The CHIPP input for the discussion of the ESPP update was then agreed during the second workshop held in September. This document describes the CHIPP position on the ESPP update focused on the scientific issues.
APPEC strongly supports and encourages the prospects of an even stronger synergy between Astroparticle Physics and Cosmology with Particle Physics. Areas of synergy between the above domains are identified: dark matter and dark energy; multi-messenger astrophysics, with the recently achieved discoveries of gravitational waves and the extraordinary opportunities also offered by gamma-ray and neutrino observatories for the exploration of powerful accelerators of the universe; the current neutrino precision program in relationship with cosmology, that promise either an unprecedented confirmation of the two standard models of Particle Physics and Cosmology, or a gate to new physics beyond both. These synergies include R&D on photosensors, cryogenic and vacuum techniques, optimisation of large scale infrastructures (civil infrastructure, vacuum, cryogenics) and of their governance and long-term operation, computing strategies for analysis and handling of large volumes of data, and policies leading to open science. Their development also requires grounding fundamental science within society, including, outreach and education. In view of the above synergies the present document introduces and briefly discusses four recommendations related to the role of PP in i) the dark matter searches; ii) the multi-messenger astronomy,in particular the 3G GW experiments (ET); iii) the neutrino physics; iv) the creation of a European Center for AstroParticle Theory (EuCAPT).

Neutrinos are electrically neutral and very light elementary particles, which interact only weakly with other matter and are therefore difficult to observe. From 2025, a new neutrino experiment in the US aims contributing to a better understanding of the neutrinos. At the University of Bern physicists are currently working on the prototype for a detector to be used in the upcoming experiment.
IPPOG, the International Particle Physics Outreach Group, is a collaboration comprising 27 signing member-organizations (countries, laboratories, experiments) whose goal is to maximize the impact of education and outreach efforts related to particle physics.
PiA offers 24 entertaining physics experiments to do yourself again this year. Due to the great interest from abroad, physics will be available in English during Advent, just like last year.
Laetitia Laub was born and raised near Lausanne. She studied mathematics and physics at the Federal Institute of Technology in Lausanne (EPFL). Since August 2017, the 24-year-old junior scientist is writing her doctoral thesis in theoretical physics at the University of Bern. In her thesis she deals with the anomalous magnetic dipole moment of the muon and the reaction of this particle in the magnetic field. "Many people are currently working on this theoretical problem with the aim of further reducing the calculation error of the dipol moment. This is also because a better experimental value for the dipole moment will be probably found at Fermilab in the US and J-Parc experiment in Japan soon, " says Laetitia Laub.
The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics 2018 with one half to Arthur Ashkin (USA) and the other half jointly to Gérard Mourou (France) and Donna Strickland (Canada). Ashkin invented optical tweezers that grab particles, atoms, viruses and other living cells with their laser beam fingers. Mourou and Strickland paved the way towards the shortest and most intense laser pulses ever created by mankind.
At the end of August, climate change and the future energy supply of Switzerland were among the topics of several keynote speeches at the Annual Meeting of the Swiss Physical Society (SPS) and the Swiss Institute of Particle Physics (CHIPP) in Lausanne. Maurice Bourquin, former professor of physics at University of Geneva, gave a keynote lecture about the ongoing transformation of the Swiss energy system. Professor Bourquin was also Rector of the University of Geneva (1999 - 2003) and President of the CERN Council (2001 - 2003). The 77 year-old scientist’s speech was titled: “Thorium-based systems – A new direction for nuclear waste elimination and energy production.” In the interview that follows, Professor Bourquin explains why he still believes in nuclear power.
