Affleck Dine baryogenesis in anomaly-mediated supersymmetry breaking
Abstract
It is known that in the anomaly-mediated supersymmetry breaking model, Affleck Dine baryogenesis does not work due to trapping of the Affleck Dine field into charge breaking minima. We show that when the finite-temperature effect is properly taken into account and if the reheating temperature is relatively high, the problem of falling into charge breaking global minima can be avoided and hence Affleck Dine baryogenesis works. Moreover, for the LHu flat direction we obtain a constraint on the mass of the neutrino.
