Abstract
In this work we investigate the chemical and kinetic nonequilibrium dynamics of the Higgs boson during the primordial Universe QGP (quark-gluon plasma) epoch . We show that the Higgs bosons is always out of chemical abundance equilibrium with a fugacity due to virtual decay channels. Additionally, Higgs momentum distribution is found to be ``cold'' for \,GeV, since the scattering rate drops below the production rate.
