Electric Dipole Moments and the Origin of Baryonic Matter
Abstract:
Explaining the origin of the excess of matter over antimatter remains an important, open problem at the interface of nuclear physics, particle physics, and cosmology. While the Standard Model contains all the necessary ingredients to provide such an explanation, the strength of its CP-violating effects are too weak to generate successful baryogenesis.
New searches for the permanent electric dipole moments (EDMs) of the neutron, charged leptons, and neutral atoms will probe for non-Standard Model CP-violation with unprecedented precision. In principle, these experiments could uncover the CP-violation needed to explain the mater-antimatter asymmetry. In this talk, I will discuss recent theoretical developments in computing the matter-antimatter asymmetry and the corresponding, prospective implications of the new EDM searches.
