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.

Stefano Marzari, a Mechanical engineer trained at the EIF (Engineering School of Fribourg), helped to set up the CERN-MEDICIS facility. In the picture, Marzari shows the first 155Tb isotope plate produced by CERN-MEDICIS on December 11, 2017. 155Tb has a half-life period of around five days; the radioactive emissions of the sample produced in December is almost completely finished.

Drugs from the particle physics research lab

CERN in Geneva is the world's largest facility for the study of fundamental particles. The equipment that usually serves science can sometimes be used for practical purposes too. That's for example the case for the protons emerging from the Proton Synchrotron Booster (PSB): they are used in the large particle accelerator LHC for scientific experiments. The protons can also be used to produce isotopes that are useful in radiation medicine. Such isotopes are produced in the recently opened facility CERN-MEDICIS.

American Physical Society (APS) April Meeting in Columbus, Ohio

The APS April Meeting encapsulates the full range of physical scales, from “Quarks to the Cosmos (Q2C)". Research will be presented on topics from 19 participating APS units including particle physics, nuclear physics, astrophysics, and gravitation. The 2018 theme is a "Feynman Century," which will be broadly examined through speakers and scientific sessions.

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.

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.
