Observation of the decay Bs0 → ηcϕ and evidence for Bs0 → ηcπ+π−

Abstract:

A study of Bs0 → ηcϕ and Bs0 → ηcπ+π− decays is performed using pp collision data corresponding to an integrated luminosity of 3.0 fb^−1 , collected with the LHCb detector in Run 1 of the LHC. The observation of the decay Bs0 → ηcϕ is reported, where the ηc meson is reconstructed in the pp, K+K−π+π−, π+π−π+π− and K+K−K+K decay modes and the ϕ(1020) in the K+K− decay mode. The decay Bs0→J/ψϕ is used as a normalisation channel. Evidence is also reported for the decay Bs0 → ηcπ+π− , where the ηc...
