Abstract
We have derived an effective potential for inflationary scenario from torsion and quantum gravity correction in terms of the scalar field hidden in torsion. A strict bound on the CP violating θ parameter, \( \mathcal{O}\left(1{0}^{-10}\right)<\theta <\mathcal{O}\left(1{0}^{-9}\right) \) has been obtained, using Planck+WMAP9 best fit cosmological parameters.
