Particle Dark Matter Density and Entropy Production in the Early Universe

Particle Dark Matter Density and Entropy Production in the Early Universe

Dark Matter (DM) density is reduced if entropy production takes place after DM particles abundance is frozen out in the early universe. We study a possibility of such reduction due to entropy production in the electroweak phase transition (EWPT). We compare scenarios of entropy production in the sta...
