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 ( n s ( 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 n s − N , r − N , d n s d ln κ − N , d n s d ln κ − n s and f N L − n s . These planes show the viability of our outcomes with Planck data 2018.
