Numerical analysis of the generalized Starobinsky inflationary model

Abstract:

In this work, we study numerically one kind of generalization of the Starobinsky inflationary model (power-law type), which is characterized by the parameter p. In order to find the parameter p that fixes with observations, we compute the cosmological parameters AS, nS and r for several values of p < 1. We have found that the value of p = 1.0004 reproduces the value of AS, nS and r is in agreement with the current observational data.
