The lower bound ensures that the reheating expansion is not accelerated [25], while the upper bound is required to preserve causality. We also introduce an additional key parameter,δ, which represents the efficiency of the preheating process relating the energy density at the end of inflation,ρ end, to that at the end of preheating,ρ pre [42].
