QFT approach to dressed particle processes in preheating and non-perturbative mechanism in kinematically-forbidden regime

Abstract We provide a quantum-field theoretic formulation of dressed particle dynamics that systematically includes particle production and scattering/decay processes in the preheating era. Our approach is based on the so-called perturbation theory in the Furry picture, in which coherent background...
