Query: Resurrecting Quadratic Inflation in No-Scale Supergravity in Light of
  BICEP2   The magnitude of primordial tensor perturbations reported by the BICEP2
experiment is consistent with simple models of chaotic inflation driven by a
single scalar field with a power-law potential \propto \phi^n: n \simeq 2, in
contrast to the WMAP and Planck results, which favored models resembling the
Starobinsky R + R^2 model if running of the scalar spectral index could be
neglected. While models of inflation with a quadratic potential may be
constructed in simple N=1 supergravity, these constructions are more
challenging in no-scale supergravity. We discuss here how quadratic inflation
can be accommodated within supergravity, focussing primarily on the no-scale
case. We also argue that the quadratic inflaton may be identified with the
supersymmetric partner of a singlet (right-handed) neutrino, whose subsequent
decay could have generated the baryon asymmetry via leptogenesis.
