Electroweak Baryogenesis With Dark CP Violation

The asymmetry between baryon and anti-baryon remains a mystery in modern physics. Electroweak baryogenesis is a mechanism in which the extra baryon number is generated at the electroweak phase transition. To generate and preserve the baryon number to the present day, electroweak baryogenesis, like all other baryogenesis mechanisms, must satisfy the well-known "Sakharov's conditions" through a sophisticated interplay between physics within and beyond the Standard Model. This talk will give an overview of the basic elements of baryogenesis, the necessity of new physics and the rich phenomenology associated with it. As an example, I will introduce one specific electroweak baryogenesis model with the CP violation occurring in the dark sector.
