CMB constraints on the inflaton couplings and reheating temperature in α-attractor inflation
Abstract We study reheating in α-attractor models of inflation in which the inflaton couples to other scalars or fermions. We show that the parameter space contains viable regions in which the inflaton couplings to radiation can be determined from the properties of CMB temperature fluctuations, in p...
