Particle Physics

Particle physics probes the basic building blocks of matter and their interactions, which determine the structure and properties of the extreme diversity of matter in the universe. It aims at explaining what holds the world together in its most fundamental constituents.

Modern physics relies on an elegant «Standard Model of particle physics», a quantum field theory based on three symmetries and a symmetry breaking. This theory describes and explains magnificently all experimental results obtained so far. With the discovery of the Higgs particle in 2012 at the Large Hadron Collider at CERN, the last missing piece of the Standard Model has been experimentally confirmed. Experiments at CERN and at other international laboratories now continue to test the validity and limits of the Standard Model in ever widening scope. However, for a comprehensive understanding of the laws of nature a theory beyond the Standard Model is needed, which should include gravitation and explain the presence of dark matter and dark energy in the universe.

The risk of thorium-based nuclear power would be acceptable

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.

Erleben Sie das grösste Physik-Laboratorium Europas

Woraus bestehen wir? Wie entstand unser Universum? Diese Fragen treibt uns doch alle um und gehören zu den grossen Rätseln der Menschheit. Am europäischen Zentrum für Nuklearforschung (CERN) in Genf wird seit 1954 auf höchsten Niveau Teilchenphysik auf faszinierende Weise betrieben. Die knapp 27 Kilometer lange Anlage des LHCs lässt dabei die Physiker seit 2010 ganz neue Welten der Physik erforschen und Fragen nach der Materie und deren Ursprung klären.

Claudia Tambasco honoured with CHIPP Prize 2018

In order for physicists at CERN to carry out their experiments for the understanding of matter, the large particle accelerator LHC must be operated with the utmost precision. Ensuring this precision both now and in the future was the overriding goal of a doctoral thesis that Claudia Tambasco recently completed at the EPFL in Lausanne. For this work, the young researcher was today (28.08.2018) awarded the prize of the Swiss Institute of Particle Physics (CHIPP) at a ceremony in Lausanne.

Long-sought decay of Higgs boson observed

Geneva, 28 August. Six years after its discovery, the Higgs boson has at last been observed decaying to fundamental particles known as bottom quarks. The finding, presented today at CERN by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC), is consistent with the hypothesis that the all-pervading quantum field behind the Higgs boson also gives mass to the bottom quark. Both teams have submitted their results for publication today.

Elementarteilchen erobern die 200-Franken-Note

Am 22. August bringt die Schweizerische Nationalbank die neue 200-Franken-Note in Umlauf. Auf der neuen Banknote wird die wissenschaftliche Schweiz durch die Elementarteilchenphysik repräsentiert. Die Auswahl dieses Sujets ist Ausdruck des hohen Stellenwerts, den die teilchenphysikalische Grundlagenforschung in der Schweiz geniesst.

Open Data and Data Management - Issues and Challenges

The SCNAT is organizing this one day event in Bern, with the aim to give the research community the chance to raise their concern and also the SNF and the European Commission to present their view and to inform about recent trends. The workshop should provide recommendations on how to implement the open data requirements.

Swiss physicists in dialog with the society

Swiss physicists want to make their fascinating research understandable to the interested public and to debate its meaning for our society together with representatives of other fields.
