We calculate numerically the electrical conductivity σ, heat conductivity κ and shear viscosity η of the hot plasma present in the early universe for the temperature interval 1 MeV ∼ T ∼ 10 GeV. We use the Boltzmann collision equation to compute all the scattering matrix elements and regulate them by the thermal masses of the tand u-channel particles. No… CONTINUE READING
