“…Such a type of rare semileptonic B decay induced by quark level transition are comparatively clean than the hadronic transitions and so it is expected that they are sensitive to some new interactions, such as 2HDM [23], supersymmetric theories [24], leptoquarks [25], non-universal model [26] , single universal extra dimension [27] etc. Another type of such semileptonic rare B decays having quark level transition are studied in various models, as scalar leptoquarks [28], supersymmetric [29], single universal extra dimension [30], non-universal Z' model and universal extra dimension model [31] and 331-Z' model [32].…”

Rare B meson decays mediated by flavour changing neutral current (FCNC) transition play interesting role to probe the flavour sector of the standard model (SM). Generally at the tree level, FCNC processes are not allowed in the SM but occurs at the loop levels. This gives an excellent hunting ground for new physics (NP). From various experimental studies it is found that the FCNC processes having quark level transition are challenging. Here, we investigate different kinematic observables like forward-backward asymmetry, differential branching ratio and lepton polarization asymmetry for semileptonic rare B decay modes and considering the contribution of Z-mediated FCNC. A noticeable deviation of the observables for these decay channels from the SM value is found because of non-universal coupling.

In this paper, we studied systematically the semileptonic decays B s ⟶ ϕ l + l − with l − = e − , μ − , τ − by using the perturbative QCD (PQCD) and the “PQCD+Lattice” factorization approach, respectively. We first evaluated all relevant form factors F i q 2 in the low- q 2 region using the PQCD approach, and we also took the available lattice QCD results at the high- q 2 region as additional input to improve the extrapolation of F i q 2 from the low- q 2 region to the endpoint q max 2 . We then calculated the branching ratios and many other physical observables A FB l , F L ϕ , S 3 , 4 , 7 , and A 5 , 6 , 8 , 9 and the clean angular observables P 1 , 2 , 3 and P 4 , 5 , 6 , 8 ′ . From our studies, we find the following points: (a) the PQCD and “PQCD+Lattice” predictions of B B s ⟶ ϕ μ + μ − are about 7 × 1 0 − 7 , which agree well with the LHCb measured values and the QCD sum rule prediction within still large errors; (b) we defined and calculated the ratios of the branching ratios R ϕ e μ and R ϕ μ τ ; (c) the PQCD and “PQCD+Lattice” predictions of the longitudinal polarization F L , the CP-averaged angular coefficients S 3 , 4 , 7 , and the CP asymmetry angular coefficients A 5 , 6 , 8 , 9 agree with the LHCb measurements in all considered bins within the still large experimental errors; and (d) for those currently still unknown observables R ϕ e μ , R ϕ μ τ , A FB l , P 1 , 2 , 3 , and P 4 , 5 , 6 , 8 ′ , we suggest LHCb and Belle-II Collaboration to measure them in their experiments.

Analysis of B _s →φμ ⁺ μ ⁻ decay within supersymmetry

Abstract: Motivated by the first measurement on B(B s → φµ + µ − ) by the CDF Collaboration, we study the supersymmetric effects in semi-leptonic B s → φµ + µ − decay. In our evaluations, we analyze the dependences of the dimuon invariant mass spectrum and the forward-
