Simulations of Cold Electroweak Baryogenesis
Anders Tranberg, Jan Smit
TL;DR
This paper uses real-time lattice simulations to explore Cold Electroweak Baryogenesis, focusing on how CP-violation and the Higgs-to-W-mass ratio influence baryon asymmetry generation.
Contribution
It provides new simulation results on the dependence of baryogenesis mechanisms on CP-violation and Higgs-to-W-mass ratio within a minimal Standard Model extension.
Findings
Baryon asymmetry varies with CP-violation strength
Higgs-to-W-mass ratio significantly affects baryogenesis efficiency
Simulation results support viability of Cold Electroweak Baryogenesis
Abstract
Cold Electroweak Baryogenesis is an attempt to explain the cosmological baryon asymmetry using only a minimal extension of the Standard Model. The relevant processes take place out of thermal equilibrium and are non-perturbative, and so must be studied using full, real-time lattice simulations. We present new results on the dependence on CP-violation and the Higgs-to-W-mass ratio
