| Popis: |
Several anomalies have been observed in various lepton non universality (LNU) observables and other asymmetries associated with semileptonic B-meson decays mediated by \(b\rightarrow (c,s)\) quark level transitions. In this context we perform a model independent analysis of \(\bar{B} \rightarrow \rho \ell \bar{\nu }_\ell \) decay process mediated by \(b\rightarrow u\) 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). |
