Dark Universe

In this talk I will discuss particle physics scenarios connecting baryogenesis with first order phase transition. In particular, I will focus on the scenario wherein the CP violation required for baryogenesis is produced by the collision of true vacuum bubbles. I will elaborate both on the case where the right handed neutrino responsible for lepton number violation is produced on-shell as well...

1. Rekindling s-Wave Dark Matter Annihilation Below 10 GeV with Breit-Wigner Effects

Dark Universe

Thermal Dark Matter (DM) below the GeV scale faces strong cosmological and astrophysical constraints, with Cosmic Microwave Background (CMB) observations excluding s-wave annihilation cross-sections for thermal DM below 10 GeV. Such limits can be evaded with velocity dependent cross-sections, for example when DM annihilates near a narrow resonance. In this work, we explore the impact of...
