Abstract

We scrutinize the penguin dominated Bs→K+K-decay mode involving b→s quark level transition in family nonuniversal Z′ and vectorlike down quark model. There is discrepancy in the standard model branching ratio value of this mode with the experimental results reported by Belle, CDF, and LHCb Collaborations. Additionally, the measured values of CP-violating asymmetries CK+K- A nd SK+K-deviate from the SM predictions. We constrain the new parameter space by using the existing experimental limits on leptonic Bs→(μ,τ) processes. We then check the effects of new physics on the branching ratio and CP-violating parameters of the Bs→K+K-process. © 2020 authors. Published by the American Physical Society.
