The nEDM experiment at the Paul Scherrer Institute

Abstract

The quest for a non-zero electric dipole moment (EDM) of simple systems such as the electron, the neutron or atoms / molecules is a pow- erful way to search for physics beyond the standard model (SM) in par- ticular for new sources of CP violation, complementary to LHC exper- iments. So far, no EDM signal was observed and the upper limit on the neutron EDM, established by the RAL/Sussex/ILL collaboration, is jdnj < 3 x 10e-26 e cm(90% C.L.). This limits was set with an apparatus using ultra cold neutrons stored in a vessel at room temperature. The nEDM collaboration at the Paul Scherrer Institute in Switzerland aims at reaching a sensitivity in the 10e-27 e cm range soon. I will present the current status of the experiment and discuss the prospects for the future.
