Abstract

We discuss in detail the search for a permanent electric dipole moment (EDM) of the 199Hg atom reported by Griffith. The upper bound, d ⁽199Hg)<3.1×10^-29 e cm (95% C.L.), is a factor of 7 improvement over the best previous EDM limit for 199Hg, provides the most sensitive probe to date for EDMs in diamagnetic atoms, and sets new limits on time-reversal symmetry violation in extensions to the standard model. This paper provides extensive discussion of the techniques used to search for the 199Hg EDM and the implications of the new 199Hg EDM limit for CP violation in elementary particle interactions.
