Özet
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--1020 MeV|<10 MeV. 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(Bs 0→J/ψf0)B(f0→π+π-)/B(Bs 0→J/ψφ)B(φ→K+K-) = 0.140±0.008(stat) ± 0.023(syst), where the first uncertainty is statistical and the second is systematic.
