Quantum Gravity Effect in Torsion Driven Inflation and CP violation
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, O(10-10)<θ< O(10-9) has been obtained, using Planck+WMAP9 best fit cosmological parameters.
