Particle production from phase transition bubbles
Henda Mansour, Bibhushan Shakya
Abstract
While first order phase transitions (FOPTs) have been extensively studied as promising cosmological sources of gravitational waves, the phenomenon of particle production from the dynamics of the background field during FOPTs has received relatively little attention in the literature, where it has only been studied with semianalytic estimates in some simplified settings. This paper provides improved numerical studies of this effect in more realistic frameworks, revealing important qualitative details that have been missed in the literature. We also provide easy to use analytic formulas that can be used to calculate particle production in generic FOPT setups.
