Fundamental Neutron Physics

The Fundamental Neutron Physics Group of Prof. Florian Piegsa develops new experiments and scientific methods in the laboratories at the University of Bern and performs measurements at international neutron research facilities.

We are using cold and ultracold neutrons to investigate the fundamental properties of the neutron itself. Hereby, we employ highly susceptible devices and installations in order to search for signals of new physics beyond the standard model of particle physics. This represents important complementary science with respect to ongoing high-energy particle physics activities, for instance performed at the Large Hadron Collider at CERN. Currently, we are involved in two low-energy neutron particle physics experiments - both have the goal to search for a neutron electric dipole moment (EDM).
