Abstract

The BICEP2 /Keck + PLANCK joint analysis of the Bmodel polarization and polarization by foreground dust sets an upper bound on the tensortoscalar ratio of r 005 012 at 95 CL The popular Starorbinsky model Higgsinflation or the conformally equivalent Higgsinflation model allow low r values ∼ 10−3 We survey the generalizations of the Starobinsky–Higgs models which would allow larger values r ∼ 01 The Starobinsky–Higgs inflation models require an exponential potential which can be naturally derived from SUGRA models We show that a variation of the noscale SUGRA model can give rise to the generalized Starobinsky models which give large r We also examine nonstandard boundary conditions which would allow a large deviation of the tensor spectral index from the slow roll values and propose that the presence of a thermal component in the tensor spectrum arises from Gibbons–Hawking temperature of the deSitter space
