Abstract

In this paper, an analysis of the Bs→ϕℓ+ℓ−B_s\to \phi \ell^+ \ell^- rare decay is presented within the framework of the covariant confined quark model. The Bs→ϕB_s\to \phi transition form factors are calculated and then used to compute the branching fractions and angular observables in various q2q^2 bins, including the forward-backward asymmetry AFBA_{FB}, the longitudinal polarization FLF_L, and the optimized observables AiA_i and SiS_i. The results show agreement with the latest experimental data given by LHCb collaboration and compared with available theoretical predictions.
