μ-hybrid inflation with low reheat temperature and observable gravity waves.

In μ-hybrid inflation a nonzero inflaton vacuum expectation value induced by supersymmetry breaking is proportional to the gravitino mass m3/2, which can be exploited to resolve the minimal supersymmetric standard model μ problem. We show how this scenario can be successfully implemented with m3/2~1-100 TeV and reheat temperature as low as 106 GeV by employing a minimal renormalizable superpotential coupled with a well-defined nonminimal Kähler 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. [ABSTRACT FROM AUTHOR]
