Miguel Escudero, "Minimal Genesis of Asymmetric Dark Matter and its signatures at the LHC and Direct Detection experiments"

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 at direct detection dark matter experiments, and we predict a new inert Higgs doublet which can be as light as 46 GeV and as heavy as 580 GeV. I will discuss the phenomenology of this model [2610.14178], including key signatures from the new Higgs at the LHC from disappearing charge tracks or displaced pions as well as its motivation and potential to successfully describe the high energy recoil event recently observed at LZ.
