QCD contributions to the thermal history of the early Universe

Abstract

We discuss the deviations from the ideal relativistic thermal bath. These deviations are dominated from quantum chromodynamic (QCD) corrections in the most part of the parameter space of the Standard Model (SM) and the Minimal Supersymmetric Standard Model (MSSM). These effects are relevant for astrophysical precision measurements and dynamics of scalar tensor theories (SST).
