Short summary
Planck 2015 full mission data reveal a spectral index of curvature perturbations ns = 0.968 ± 0.006 and constrain its scale dependence to dns/dlnk = −0.003 ± 0.007, disfavoring models like V(φ) ∝ φ² and natural inflation in favor of those predicting smaller tensor-to-scalar ratios (r < 0.11).
