SUMMARY:Baryogenesis in the 2HDM+a - Tom Gent (University of Sussex)

CONTACT:Benjamin Christopher Allanach
DESCRIPTION:In this talk\, I will introduce a particular beyond the Standa
 rd Model extension: the 2HDM+a\, a non-minimal Higgs sector consisting of
  two Higgs doublets and a singlet pseudoscalar\, a. I will explain how the
  baryon asymmetry of the Universe can be produced in this model through el
 ectroweak baryogenesis and the mechanism of transient CP violation\, which
  naturally avoids electric dipole moment constraints. Theoretical benchmar
 ks created using state-of-the-art methods are then scrutinised with LHC se
 arches and low-energy flavour measurements\, leading to viable and predict
 ive scenarios that are testable in the future.
