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.

PiA - Physics in Advent: still 24 experiments until Christmas

PiA offers 24 entertaining physics experiments to do yourself again this year. Due to the great interest from abroad, physics will be available in English during Advent, just like last year.

Gehen die Malediven unter? Steht New York bald unter Wasser?

Aufgrund des Klimawandels sind die Wassertemperaturen der Ozeane im Steigen begriffen. Deshalb schmelzen nicht nur die Alpengletscher weitgehend ab, sondern auch die Eismassen der Polargebiete werden immer kleiner. Dieser zusätzliche Wassereintrag in die Weltmeere und das grössere Volumen der wärmeren Wassermassen führen dazu, dass ganze Küstenregionen im Meer versinken werden.

Further reducing the error

Laetitia Laub was born and raised near Lausanne. She studied mathematics and physics at the Federal Institute of Technology in Lausanne (EPFL). Since August 2017, the 24-year-old junior scientist is writing her doctoral thesis in theoretical physics at the University of Bern. In her thesis she deals with the anomalous magnetic dipole moment of the muon and the reaction of this particle in the magnetic field. "Many people are currently working on this theoretical problem with the aim of further reducing the calculation error of the dipol moment. This is also because a better experimental value for the dipole moment will be probably found at Fermilab in the US and J-Parc experiment in Japan soon, " says Laetitia Laub.

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.
