Abstract: We study the Planck scale effects on Jarlskog determinant. Quantumgravitational Planck scale effects lead to an effective SU2 {L}\times U1invariant dimension-5 Lagrangian involving neutrino and Higgs fields, whichgives rise to additional terms in neutrino mass matrix on electroweak symmetrybreaking. We assume that gravitational interaction is flavor blind and computethe Jarlskog determinant due to the Planck scale effects. In the case ofneutrino sector, the strength of CP violation is measured by Jarlskogdeterminant. In this paper, we assume CP violation arise from Planck scaleeffects. We applied our approach to study Jarlskog determinant due to thePlanck scale effects.
