摘要
In mu-hybrid inflation a nonzero inflaton vacuum expectation value induced by supersymmetry breaking is proportional to the gravitino mass m(3/2), which can be exploited to resolve the minimal supersymmetric standard model mu problem. We show how this scenario can be successfully implemented with m(3/2) similar to 1-100 TeV and reheat temperature as low as 10(6) GeV by employing a minimal renormalizable super-potential coupled with a well-defined nonminimal Kahler potential. The tensor-to-scalar ratio r, a canonical measure of primordial gravity waves, in most cases is less than or of the order of 10(-6)-10(-3).
