Abstract
We report the results of a new experimental search for a permanent electric dipole moment of utilizing a stack of four vapor cells. We find , and interpret this as a new upper bound, (95% C.L.). This result improves our previous limit by a factor of 7, and can be used to set new constraints on violation in physics beyond the standard model.
