New Jarlskog determinant from Physics above the GUT Scal
Bipin Singh Koranga, S. Uma Sankar
We study the Planck scale effects on Jarlskog determinant. Quantum gravitational (Planck scale) effects lead to an effective SU(2)_{L}\times U(1) invariant dimension-5 Lagrangian i…
Deviation from Bimaximality due to Planck scale effects
Bipin Singh Koranga, Mohan Narayan, S. Uma Sankar
We consider the effect of Planck scale operators on neutrino mixing. We assume that GUT scale operators give rise to degenerate neutrino masses with bimaximal mixing. Quantum gravi…
Bounds on Tensor operator contribution to B_s --> l+ l- gamma
Ashutosh Kumar Alok, S. Uma Sankar
We consider the effect of new physics interactions in the form of tensor operators on the branching ratio of B_s --> l+ l- gamma where l=e, mu. We find that the present data on the…
