Abstract

We derive one-loop effective potentials in de Sitter background for scalar, fermion and gauge-boson loops. The results are applied to flat directions of the MSSM. It is found that due to Yukawa couplings, a lifting mass term of order of the Hubble rate arises. The lifting contributions mediated by the gauge couplings are found to cancel at leading order in the Hubble rate.
