Description

Extended scalar sectors can yield baryogenesis at the EW scale, by providing the needed departure from thermal equilibrium (absent in the SM) via a first-order EW phase transition. Yet, BSM sources of CP violation are also required for baryogenesis, despite being very strongly constrained experimentally by electric dipole moments (EDMs). In this talk I will discuss a CP-violating Higgs portal scenario where an extended scalar sector offers a solution to this problem too, by providing the required CP-breaking in a secluded manner - in the SM interactions with a dark sector -, and will explore the LHC searches (existing and yet non-existing) to probe such a scenario.
