Abstract

We present the first results of a new search for a permanent electric dipole moment of the

^{199} Hg

atom using a UV laser. Our measurements give

d (^{199} Hg) = - (1.06 \pm 0.49 \pm 0.40) \times 10^{- 28} e cm

. We interpret the result as an upper limit

| d (^{199} Hg) | < 2.1 \times 10^{- 28} e cm

(95% C.L.), which sets new constraints on

{\bar{θ}}_{QCD}

, chromo-EDMs of the quarks, and CP violation in supersymmetric models.
