$\mu$-Hybrid Inflation with Low Reheat Temperature and Observable Gravity Waves

Mansoor Ur Rehman, Qaisar Shafi, Fariha K. Vardag

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 res…
