Description

We consider hybrid inflation models in the framework of no-scale supergravity. $U(1)_R$ symmetry can be broken on the renormalizable level or by Planck suppressed non-renormalizable operators. We show that a Starobinsky like inflation can be realized with asymptotically flat potentials for specific region of parameter space. A connection to the low energy physics as well as the neutrino masses is addressed in a realistic GUT model.
