Generalized Hilltop Inflation

Understand

We study a generalized version of hilltop inflation where the standard hilltop potential has been raised to a power and we allow fractional numbers for both the original hilltop power ($m$) and the overall exponent ($n$).

• In the parameter space studied, agreement with the latest experimental constraints favors high values for $m$ and low values for $n$.
• Finally, we also find that in all the configurations studied, the inflationary scale always sits around the grand unification scale.
