Abstract: We generalize the effective potential to scalar field configurations whichare proportional to the Hubble parameter of a homogeneous and isotropicbackground geometry. This may be useful in situations for which curvatureeffects are significant. We evaluate the one loop contribution to the HubbleEffective Potential for a massless scalar with arbitrary conformal and quarticcouplings, on a background for which the deceleration parameter is constant.Among other things, we find that inflationary particle production leads tosymmetry restoration at late times.
