Large tensor-to-scalar ratio and running of the scalar spectral index with instep inflation

If a sizeable tensor-to-scalar ratio ~ 0.1 turns out to be detected and a negative running of the scalar spectral index ~ 10 super(-2) is significantly required by the data, the vast majority of single field models of inflation will be ruled out. We show that a flat tree-level effective potential, l...
