Measurement of the ratio B(Bs0→J/ψf0(980))/B(Bs0→J/ψϕ(1020)) in pp collisions at s=7 TeV

A measurement of the ratio of the branching fractions of the Bs0 meson to J/ψf0(980) and to J/ψϕ(1020) is presented. The J/ψ, f0(980), and ϕ(1020) are observed through their decays to μ+μ−, π+π−, and K+K−, respectively. The f0 and the ϕ are identified by requiring |Mπ+π−−974 MeV|<50 MeV and |MK+K...
