Seminar: ‘Asymmetric Dark Matter induced by Baryogenesis’

Title: ‘Asymmetric Dark Matter induced by Baryogenesis’

Speaker: Miguel Escudero (CERN)

Venue&Time: Red Room / 15:00

Abstract: We live in a Universe where structures are made out of baryons but not of antibaryons. Could the dark matter be made of particles and not antiparticles? This is an old question and many asymmetric dark matter scenarios have been proposed to date. Among them, the models where a dark matter asymmetry is induced from the baryon/lepton asymmetries are particularly motivated. In this seminar, I will highlight the motivations for these types of frameworks but also their challenges. I will then present a new, minimal, and predictive scenario that we developed in [2511.10731]. In this model, a dark matter asymmetry is slowly generated from the Standard Model Higgs doublet asymmetry. The scenario features two dark matter states which can lead to signals in the next generation of dark matter experiments, and we predict a new inert Higgs doublet with mass < 580 GeV which could be produced and observed at the LHC and future colliders.
