Precision physics with cold neutrons

The investigation of the standard model of particle physics, its symmetries, interactions and particle properties, is a central theme of modern physics. When testing it with ever increasing precision we hope to find deviations from its predictions which may point to physics beyond the standard model. This will lead us to an even better and deeper understanding of the microscopic world and to an even simpler and more concise model of the elementary particles and their interactions. Precision experiments at low energies, like in beta-decay1(click here for more information), complement the searches for new physics at high energies, like at the LHC. The neutron, as the most simple nucleus, offers great opportunities for such low energy precision experiments2.

We have two projects in the field of fundamental physics with cold neutrons:
