arXiv:2310.05987 · doi:10.1088/1674-1137/ad010f
Abstract
In this article, we explore the concept of cosmological inflation within the framework of the theory of gravity, where is a general function of the Torsion scalar and the trace, , of the energy-momentum tensor. It is assumed that the conditions of slow-roll inflation are applicable in gravity. To determine different observables related to inflation, such as the tensor-to-scalar ratio , scalar spectral index , spectral index , and tensor spectral index , the Hubble slow-roll parameters are utilized for a particular model of . Lastly, an assessment has been carried out to determine the feasibility of the models by conducting a numerical analysis of the parameters. The findings indicate that it is feasible to achieve compatibility with the observational measurements of slow-roll parameters by utilizing different values of the free parameters.
