Description
We report the results of a new experimental search for a permanent electric dipole moment of 199Hg utilizing a stack of four vapor cells. We find d(199Hg)=(0.49±1.29stat±0.76syst)x10-29 e cm, and interpret this as a new upper bound, |d(199Hg)|<3.1x10-29 e cm (95% C.L.). This result improves our previous 199Hg limit by a factor of 7, and can be used to set new constraints on CP violation in physics beyond the standard model
