| contents | By applying a particular kind of modified gravity, we study the inflation. Precisely, we extend our investigations beyond the Einstein's gravity to explore the Natural inflation model via the term $F(ϕ)T$. We compute the inflation dynamics to derive the slow-roll parameters, i.e., the tensor-to-scalar ratio ``$r$'' and the scalar spectral index ``$n_s$''. This modified form of the gravity yields not only the predictions of the original models but also better-fitting with the Planck/BICEP/Keck data. |
