On the large-field equivalence between Starobinsky and Higgs inflation in gravity and supergravity
March 03, 2022
Starobinsky inflation and Higgs inflation are reviewed with the focus on their equivalence in the large field limit due to the common inflaton scalar potential. This asymptotic equivalence is extended to supergravity in the minimal framework, where the Starobinsky and Higgs descriptions of inflation arise in two different gauges of a single model.
