Abstract: (arXiv)
The observables T/ST/S and n1n-1 are key to testing and understanding inflation. (TT, SS, and n1n-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/ST/S and n1n-1. By reformulating the equations governing inflation we show that models generally predict T/S5(n1)T/S \approx -5(n-1) or 0, and in particular, if n>0.85n>0.85, T/ST/S is expected to be >103>10^{-3}.
