An analytic treatment of Quartic Hilltop Inflation

Understand

Quartic hilltop inflation remains one of the most successful inflationary models.

• Yet, the expectations of early treatments of hilltop inflation would contradict the observations and render the model excluded.
• However, recent numerical treatment has demonstrated that quartic hilltop inflation actually fares well with observations.
• In this work, a fully analytic treatment of the model aims to dispel the mystery surrounding the behaviour of quartic hilltop inflation.
