Observable r, gravitino dark matter, and non-thermal leptogenesis in no-scale supergravity
Abstract We analyse the shifted hybrid inflation in a no-scale supersymmetric SU(5) GUT model which naturally circumvents the monopole problem. The no-scale framework is derivable as the effective field theory of the supersymmetric (SUSY) compactifications of string theory, and yields a flat potenti...
