Model independent analysis of $B^{\ast }\to P\ell {\bar{\nu }}_{\ell }$ decay processes

Atasi Ray, Suchismita Sahoo, Rukmani Mohanta

Very compelling deviations in the recently observed lepton nonuniversality observables $(R_{D^{(\ast )}},R_{K^{(\ast )}},R_{J/\psi })$ of semileptonic $B$ meson decays from their…
