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\theta parameter, O(1010)<θ<O(109){\cal O}(10^{-10})<\theta<{\cal O}(10^{-9}) has been obtained, using {\tt Planck+WMAP9} best fit cosmological parameters.
