AB - We study the sensitivity of cosmological observables to the reheating phasefollowing inflation driven by many scalar fields. We describe a method whichallows semi-analytic treatment of the impact of perturbative reheating oncosmological perturbations using the sudden decay approximation. Focusing on$\calN$-quadratic inflation, we show how the scalar spectral index andtensor-to-scalar ratio are affected by the rates at which the scalar fieldsdecay into radiation. We find that for certain choices of decay rates,reheating following multiple-field inflation can have a significant impact onthe prediction of cosmological observables.
