Abstract

The Standard Model of particle physics is known to be incomplete. Extensions to the Standard Model, such as weak-scale supersymmetry, posit the existence of new particles and interactions that are asymmetric under time reversal (T) and nearly always predict a small yet potentially measurable electron electric dipole moment (EDM), d_e, in the range of 10^-27 to 10^-30 e.cm. The EDM is an asymmetric charge distribution along the electron spin (S^→) that is also asymmetric under T. Using the polar molecule thorium monoxide, we measured d_e = (-2.1 ± 3.7_stat ± 2.5_syst) x 10^-29 e.cm. This corresponds to an upper limit of |d_e| <8.7 x 10^-29 e.cm with 90% confidence, an order of magnitude improvement in sensitivity relative to the previous best limit. Our result constrains T-violating physics at the TeV energy scale.
