Quadratic, Higgs and hilltop potentials in Palatini gravity

Nilay Bostan

Figure 2. The figure shows that ns − r predictions for quadratic potential in the Palatini formalism for high-N scenario for the different ξ values that are mentioned in the text. The pink (red) contour correspond to the 95% (68%) CL contour given by the Keck Array/BICEP2 and Planck collaborations [10].
