Attractor and slow roll parameterized inflation in extended teleparallel gravity

Abstract

The study of inflation through different prospects is being done for specific model of scalar f(T) gravity in two phases such as attractor (ns(N)−1∝N−1) and slow roll parameterizations. In the presence of these ingredients, we evaluate all inflationary parameters such as scalar spectral index, tensor to scalar ratio r and running of scalar spectral index and local non Gaussianity parameter. We also develop the inflationary planes ns−N, r−N, dnsdlnκ−N, dnsdlnκ−ns and fNL−ns. These planes show the viability of our outcomes with Planck data 2018.
