Abstract

We perform a global fit using results of searches for electric dipole moments (EDM) of diamagnetic systems within the context of the minimal left-right symmetric model. In this way, we disentangle the new "left-right" electroweak and θˉ\bar{\theta} contributions that cannot be separated using a single EDM system. Although the fit is done for a specific model, the approach can be applied to any particle physics model. Finally, we revisit the constraint on the DD coefficient in β\beta-decay and find that current EDM bounds do not preclude observation of this T-violating effect in a possible next generation β\beta-decay experiment.
