Quadratic, Higgs and hilltop potentials in Palatini gravity

Nilay Bostan

Figure 4. For Higgs potential in the Palatini formalism in the cases of φ > v and high-N scenario, in the top figures display changing ns and r values for different ξ cases as function of v and the bottom figure shows that ns − r predictions for selected ξ values. The pink (red) contour correspond to the 95% (68%) CL contour given by the Keck Array/BICEP2 and Planck collaborations [10].
