چکیده انگلیسی
We reconsider the Polonyi problem in gravity-mediation models for supersymmetry (SUSY) breaking. It has been argued that there is no problem in the dynamical SUSY breaking scenarios, since the Polonyi field acquires a sufficiently large mass of the order of the dynamical SUSY-breaking scale ÎSUSY. However, we find that a linear term of the Polonyi field in the Kähler potential brings us back to the Polonyi problem, unless the inflation scale is sufficiently low, Hinfâ²108GeV, or the reheating temperature is extremely low, TRâ²100GeV. Here, this Polonyi problem is more serious than the original one, since the Polonyi field mainly decays into a pair of gravitinos.
