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.

Symposium zur Erinnerung an Jean-Pierre Blaser

Jean-Pierre Blaser war der Gründungsdirektor vom Paul Scherrer Institut (PSI) und davor vom Schweizerische Institut für Nuklearforschung (SIN). Er ist am 29. August 2019 im alter von 96 Jahre verstorben. Das Gedächtnissymposium in Zürich soll in mehreren Vorträgen an die technischen, wissenschaftlichen und geschichtlichen Entwicklungen am SIN und während der Anfangsjahre am PSI erinnert werden.

Physik am Freitag 2020

Seit mehr als 10 Jahren bieten die Physikalischen Institute der Universität Bern an fünf Freitagen ab 16:30 Uhr eine Reihe von fünf öffentlichen Vorträgen an, in denen aktuelle Forschungsergebnisse der Physik erläutert werden. Die Vorträge werden in der Regel auf Deutsch gehalten und dauern etwa eine Stunde, gefolgt von Fragen und kleinen Erfrischungen.

Rainer Wallny on the CERN Future Circular Collider (FCC) project

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.

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.
