Search for the permanent electric dipole moment of $^{129}$Xe
ORAL
Abstract
CP-violation in Beyond-the-Standard-Model physics, necessary to explain the baryon asymmetry, gives rise to permanent electric dipole moments (EDMs). EDM measurements of the neutron, electron, paramagnetic and diamagnetic atoms constrain CP-violating parameters. The current limit for the $^{129}$Xe EDM is $6\times10^{-27}~e\cdot\mathrm{cm}$ (95$\%$ CL). The HeXeEDM experiment at FRM-II (Munich Research Reactor) and BMSR-2 (Berlin Magnetically Shielded Room) uses a stable magnetic field in a magnetically shielded room and $^3$He comagnetometer with potential to improve the limit by two orders of magnitude. Polarized $^3$He and $^{129}$Xe free precession is detected with SQUID magnetometers in the presence of applied electric and magnetic fields. Conclusions from recent measurements will be presented.
