Search for- or measurement of- the neutron electrical dipole moment


Abstract:
Very narrow constraints are set by values of Electrical Dipole Moments 
(EDMs), as they brake parity and time-reversal symmetries, on the models 
beyond standard model (SM) of particle physics. They must include low 
level of CP (charge, parity) violation in K  (decays of the neutral K 
mesons) and B (beauty mesons) systems and to explain the large baryon 
asymmetry of the Universe in the same time. The current limit of the 
neutron Electrical Dipole Moment (nEDM) has already set requirements for 
considerable fine-tuning of MSSM parameters - the so-called "SUSY CP 
problem.

The most sensitive nEDM experiment was operated by nEDM international 
collaboration (2015-2017, results to be submitted shortly) at the Paul 
Scherrer Institute (PSI) in Switzerland. Currently the nEDM 
collaboration is constructing improved version of the experiment (n2EDM) 
using the same PSI infrastructure.

In my talk I will present the old nEDM experiment at PSI and its 
improvements towards n2EDM. From December 2018 the Institute of Physics 
Belgrade is full member of the nEDM collaboration with Dr. Zoran D. 
Grujić as its representative.
