Higgs Thermal Nonequilibrium in Primordial QGP

In this work we investigate the chemical and kinetic nonequilibrium dynamics of the Higgs boson during the primordial Universe QGP (quark-gluon plasma) epoch $130\mathrm{G}\mathrm{e}\mathrm{V}>T>10\mathrm{G}\mathrm{e}\mathrm{V}$. We show that the Higgs bosons is always out of chemical abundance equilibrium with a fugacity ${\mathrm{{\rm Y}}}_h=0.69$ 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.
