Quadratic, Higgs and hilltop potentials in Palatini gravity
Nilay Bostan
Figure 1. The figure illustrates that ns r predictions for different ξ values and v = 0.01 for various reheating cases as described in the text for Higgs potential in the Palatini formalism. The points on each curve represent ξ = 10−2.5, 10−2, 10−1.5, 10−1, and 1, top to bottom. The pink (red) contour corresponds to the 95% (68%) CL contours based on the data taken by the Keck Array/BICEP2 and Planck collaborations [10].
