Abstract: (arXiv)
The observables T/S and n−1 are key to testing and understanding inflation. (T, S, and n−1 respectively quantify the gravity-wave and density-perturbation contributions to CMB anisotropy and the deviation of the density perturbations from the scale-invariant form.) Absent a standard model, there is no definite prediction for, or relation between, T/S and n−1. By reformulating the equations governing inflation we show that models generally predict T/S≈−5(n−1) or 0, and in particular, if n>0.85, T/S is expected to be >10−3.- inflation
