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 uses a stable magnetic field in a magnetically shielded room, spin-precession detection with SQUID magnetometer arrays and a $^3$He co-magnetometer to measure the $^{129}$Xe EDM with the potential to improve the sensitivity by two orders of magnitude. Results from a June 2017 test run and plans for production data will be presented.
