In this paper we constrain some aspects of the general postinflationary phase in the context of superconformal α-attractor models of inflation. In particular, we provide constraints on the duration of the reheating process, Nreh, and on the reheating temperature, Treh, simulating possible and future results given by the next generation of cosmological missions. Moreover, we stress what kinds of equation-of-state parameter, wreh, are favored for different scenarios. The analysis does not depend on the details of the reheating phase, and it is performed assuming different measurements of the tensor-to-scalar ratio r.

Abstract

In this paper we constrain some aspects of the general postinflationary phase in the context of superconformal α-attractor models of inflation. In particular, we provide constraints on the duration of the reheating process, Nreh, and on the reheating temperature, Treh, simulating possible and future results given by the next generation of cosmological missions. Moreover, we stress what kinds of equation-of-state parameter, wreh, are favored for different scenarios. The analysis does not depend on the details of the reheating phase, and it is performed assuming different measurements of the tensor-to-scalar ratio r.
