    Abstract:
    The decay mechanisms of B s 0 → μ + μ - and B d 0 → μ + μ - in pp̄ collisions were investigated. For discrimination of the decays from background events, four variables were used such as invariant mass of muon pair, B-candidate proper decay length, opening angle between B-hadron flight direction and B-candidate track isolation. A 'blind' analysis technique was also used for determination of optimal selection criteria for four variables. The results show that optimal set of selection criteria uses ∓80 MeV/c 2 search window around B s 0 mass, and I > 0.65.
