Query: Quantum Gravity Effect in Torsion Driven Inflation and CP violation   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 $\theta$ parameter, ${\cal
O}(10^{-10})<\theta<{\cal O}(10^{-9})$ has been obtained, using {\tt
Planck+WMAP9} best fit cosmological parameters.
