Hubble-induced radiative corrections and Affleck-Dine baryogenesis

We examine the viability of the Affleck-Dine mechanism for baryogenesis under radiatively induced running of soft breaking (mass)(2) of the flat directions stemming from a nonzero energy density of the inflaton during inflation. A major difference from analogous phenomenological studies is that the horizon radius provides a natural infrared cutoff to the quantum corrections in this case. We identify different scenarios which may arise and point out that the H L-u flat direction remains the most promising flat direction, since it is largely independent of uncertainties about high scale physics and details of the inflationary model.
