Abstract

In this work, we investigate the chemical and kinetic nonequilibrium dynamics of the Higgs boson during the primordial Universe Quark-Gluon Plasma epoch 130GeV>T>10GeV. We show that the Higgs bosons are always out of chemical abundance equilibrium with a fugacity Υh=0.69 due to virtual decay channels. Additionally, Higgs momentum distribution is found to be “cold” for T<25 GeV, since the scattering rate drops below the production rate.
