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.

One focus point is the multi-messenger astronomy

On 9 January 2018 the Astroparticle Physics European Consortium (APPEC) will officially launch its new Strategy 2017-2026 in Brussels. The strategy is addressing the main scientific issues of astroparticle physics in the upcoming decade. Teresa Montaruli – physics professor at the University of Geneva and the representative of the Swiss National Science Foundation (SNF) and of the CHIPP association of professors in the APPEC General Assembly – gives an outlook on the key messages of the new strategy.

Wie gross ist das Weltall?

Erst als die Himmelskörper nicht mehr als Gottheiten verstanden wurden, der Himmel in unendliche Weiten entschwand, die Erde nicht mehr als Mittelpunkt des Universums galt, erhob sich die Frage nach den Entfernungen der Planeten und Sterne. Seit etwa 400 Jahren bemühen sich die Astronomen darum, aber die Distanzmessung ist auch heute noch nicht einfach.

Neutrinos from Nowhere

Thanks to the University of Geneva Swiss astroparticle physics participates in IceCube - a huge experiment in neutrino research at the South Pole. The scientists aim to probe with IceCube the exact origin of the neutrinos coming from the universe. For over two years the young scientist Tessa Carver (24) has been part of the experiment.

Beam Dynamics and Technologies for Future Colliders

CERN accelerator School ad Paul Scherrer Institute are organizing this course. The course will be of interest to staff and students from laboratories and universities who wish to learn about the various options being considered for future colliders for high-energy physics. The material presented will be at an accessible level and cover circular hadron and lepton colliders, as well as linear lepton colliders. The programme will cover the beam dynamics of the colliders presently under consideration and the associated technologies that will be needed to build them.
Beam generation and machine protection issues will also be addressed.
Students will have the opportunity to work on realistic case studies throughout
the school.

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.
