Effect of new physics in B→plvl Decay Process

Abstract

Several anomalies have been observed in various lepton non universality (LNU) observables and other asymmetries associated with semileptonic B-meson decays mediated by (formula presented) quark level transitions. In this context we perform a model independent analysis of (formula presented) decay process mediated by (formula presented) quark level transition. In this article, we calculate the branching fraction, lepton spin asymmetry and LNU parameter associated with this decay process and scrutinize whether there will be any deviation in these observables in presence of new Physics (NP).
