Populating secluded dark sector with ultra-relativistic bubbles
Aleksandr Azatov, Xander Nagels, Miguel Vanvlasselaer +1
We study Dark Matter production during first order phase transitions from bubble-plasma collisions. We focus on scenarios where the Dark Matter sector is secluded and its interacti…
Baryogenesis and leptogenesis with relativistic bubble walls
Miguel Vanvlasselaer
In this talk, we study the impact of first order phase transitions with fast bubble walls on mechanisms of leptogenesis and baryogenesis. We begin our exploration with the usual le…
Criterion for ultra-fast bubble walls: the impact of hydrodynamic obstruction
Wen-Yuan Ai, Xander Nagels, Miguel Vanvlasselaer
The Bödeker-Moore thermal friction is usually used to determine whether or not a bubble wall can run away. However, the friction on the wall is not necessarily a monotonous functio…
Ultra-relativistic bubbles from the simplest Higgs portal and their cosmological consequences
Aleksandr Azatov, Giulio Barni, Sabyasachi Chakraborty +2
We analyze the phase transitions in the minimal extension of the SM with a real singlet scalar field. The novelty of our study is that we identify and analyze in details the region…
