Summary:

The Standard Model (SM) of particle physics, despite its remarkable success in explaining a vast array of phenomena, remains incomplete. Crucially, it fails to account for Dark Matter (DM) and the Baryon Asymmetry of the Universe (BAU), highlighting the need for physics Beyond the Standard Model (BSM).

A necessary ingredient to dynamically generate the observed baryon–antibaryon asymmetry is the presence of additional sources of CP violation beyond those present in the SM. As a result, precision measurements of CP-odd observables serve as powerful probes of BSM scenarios. Among these, Electric Dipole Moments (EDMs) stand out as exceptionally sensitive tests of new CP-violating physics.

In this talk, I will discuss how EDM searches can probe dark sectors, which offer rich scenarios for viable DM candidates and may also introduce the necessary ingredients for successful baryogenesis. I will focus on the phenomenology of a CP violating portal between the Dark Sector and SM, possible if the Dark Sector interactions stem from a non-abelian gauge symmetry.

Finally, I will describe EDM searches in a model independent framework, using Effective Field Theories (EFT). I will discuss how, including loop effects in the EFT, EDM experiments can test a wide variety of CP-odd operators.
