Contribution of Vector Resonances to the CP-Asymmetry of the Neutral B-Meson Decay into a Muon-Antimuon Pair and a Neutral K* Meson
Section: Fields and elementary particles
Original Author's Text: Ukrainian
Abstract: Contributions of the processes B0d → K *0 (→ K−π+) V with vector mesons V = ρ (770), ω(782), φ(1020), J/ψ, ψ(2S), and others decaying into the μ+μ− pair to the CP-asymmetry in the decay B0d → K*0 (→ K¯π+)μ+μ− induced by the flavor-changing neutral currents are calculated. For the description of the transition b → sμ+μ−, the most general form of the effective weak-interaction Hamiltonian is applied. Predictions are made for the CP-asymmetry of the decay B0d → K*0 (→ K¯π+)μ+μ− in the framework of the standard model, as well for two scenarios of new physics. The obtained results are compared with experimental data of the LHCb Collaboration.
Key words: B-meson, CP symmetry, vector mesons, decay, vector-meson dominance.
