The study of NSIs in B and KL rare decays with three generations of quarks and interference effects between the standard model and NSIs

Abstract

We study the rare decays of B meson. We want to constraint the NSIs by using these reactions. We show that there is a strong dependence of these reactions on new physics parameter. We include second and third generation of quarks in the loop for these decays. We further point out that the constraints for second generation are more precise as compared to second and third. We further point out that for inclusive decay, the u quark induce NSIs are giving very very small contribution. We also study KL rare decay to pi zero, neutrino and anti-neutrino. We also study the interference between the standard model and NSIs.
