Constraints and Forecasts for Reheating in the K"ahler Moduli Inflation I Potential

(P)reheating Effects of the Kähler Moduli Inflation I Model

We investigate reheating in the string-theory-motivated string-theory-motivated kahler-moduli-inflation potential, coupled to a light scalar field and produce constraints and forecasts based on cosmic microwave background (cmb) and gravitational wave observables.

We implement a markov chain monte carlo sampling method to compute the adopted model s parameter ranges allowedby the current cmb observations.

We observe narrow-band self-resonance and parametric resonance instabilities in our floquet analysis results.

We perform numerical lattice simulations to analyze the nonlinear effects of the model s (p)reheating phase.
