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.

Research as a peace project

The laws of particle physics apply regardless of place and time, but the laws can’t be explored or their applications studied equally well in any location. Particularly in poorer countries, cost-intensive research projects face big challenges. Against this background, there is a ray of hope that the first Synchrotron in the Middle East for the production of high-brilliance X-ray radiation, called SESAME, will be launched during summer 2017. Switzerland has contributed to the success of this project.
The science fiction novel 'The Three-Body Problem' written by Cixin Liu was released in December 2016 in German (titled 'Die drei Sonnen').

Blocked future

The Chinese writer Cixin Liu has landed an international bestseller with the novel 'The Three-Body Problem'. Now his story about the fight between the Earth and the Trisolaran population is also available in German translation. In the dress of a science fiction novel, the 53-year-old author expresses his deep conviction: without fundamental research in physics, technical progress remains on the line.

"Making physics vivid and interesting"

Bahar Behzadi, physics teacher at the Freies Gymnasium Zürich, participated with her pupils in the last year's competition "Physics in Advent". The class performed excellently in the competition and was granted a visit to the Swiss Science Center Technorama in Winterthur. In the interview, the 44-year-old teacher reports on her experiences.

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.
