Abstract

We propose a minimal model framework for physics below the Planck scale with the following features: (i) it is based on no-scale supergravity, as favored in many string compactifications, (ii) it incorporates Starobinsky-like inflation, and hence is compatible with constraints from the Planck satellite, (iii) the inflaton may be identified with a singlet field in a seesaw model for neutrino masses, providing an efficient scenario for reheating and leptogenesis, (iv) supersymmetry breaking occurs with an arbitrary scale and a cosmological constant that vanishes before radiative corrections, and (v) regions of the model parameter space are compatible with all LHC, Higgs boson, and dark matter constraints.
