S-dual Inflation: BICEP2 data without unlikeliness

arXiv:1403.4578 · doi:10.1016/j.physletb.2014.05.046

Abstract

We show that S-dual inflationary potentials solve the unlikeliness problem manifested in Planck data and explain the excess B-mode power observed by the BICEP2 experiment as arising from primordial tensor fluctuations.
