Reheating constraints on K\"ahler Moduli Inflation

Understand

The end of inflation is connected to the standard cosmological scenario through reheating.

• During reheating, the inflaton oscillates around the minimum of the potential and thus decays into the daughter particles that populate the Universe at later times.
• Using cosmological evolution for observable CMB scales from the time of Hubble crossing to the present time, we translate the constraint on the spectral index $n_s$ from Planck data to the constraint on the reheating scenario in the context of K\"ahler Moduli Inflation.
• In addition, we extend the de-facto analysis generally done only for the pivot scale to all the observable scales which crossed the Hubble radius during inflation.
