Study of semileptonic decays $B \to \pi l^+ l^-$ and $B \to \rho l^+ l^-$ in non-universal Z' model

Semileptonic B meson decays induced by $b \to s (d) l^{+} l^{-}$ flavour changing neutral current (FCNC) transitions are very important to probe the quark-flavour sector of the standard model (SM) and also offer a probe to test new physics (NP). Although there exists a lot of precise results on $b \to sl^+ l^- $i n d u c e d p r o c e s s e s, t h e r e i s l a c k o f s u f f i c i e n t d a t a f o r$ b \to dl^+ l^- $i n d u c e d d e c a y s . H e r e, w e a r e i n t e r e s t e d t o s t u d y$ B \to \pi l^+ l^- $a n d$ B \to \rho l^+ l^- $d e c a y s w h i c h p r o c e e d v i a$ b \to dl^+ l^-$ transition at the quark level. In this work, we investigate the differential branching ratio, forward-backward asymmetry, CP violation asymmetry and lepton polarization asymmetry in these two decay channels in a non-universal Z’ model. We find a significant deviation from the SM value of these physical observables for these decays which provide a clear conjecture for NP arising from Z’ gauge boson.
