Measurement of the ratio B(B_{S}^{0}\rightarrow J\psi f_{0}(980))/B(B_{S}^{0}\rightarrow J\psi\phi(1020)) in pp collisions at \sqrt{s} =7 TeV

Abstract A measurement of the ratio of the branching fractions of the B s 0 meson to J / ψ f 0 ( 980 ) and to J / ψ ϕ ( 1020 ) is presented. The J / ψ , f 0 ( 980 ) , and ϕ ( 1020 ) are observed through their decays to μ + μ − , π + π − , and K + K − , respectively. The f 0 and the ϕ are identified by requiring | M π + π − − 974 xa0MeV | 50 xa0MeV and | M K + K − − 1020 xa0MeV | 10 xa0MeV . The analysis is based on a data sample of pp collisions at a centre-of-mass energy of 7 TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 5.3 fb−1. The measured ratio is B ( B s 0 → J / ψ f 0 ) B ( f 0 → π + π − ) B ( B s 0 → J / ψ ϕ ) B ( ϕ → K + K − ) = 0.140 ± 0.008 ( stat ) ± 0.023 ( syst ) , where the first uncertainty is statistical and the second is systematic.
