| dc.description.abstract | A measurement of the ratio of the branching fractions of the B0smeson 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 f0and the φare identified by requiring |Mπ+π−−974MeV| <50MeVand |MK+K−−1020MeV| <10MeV. The analysis is based on a data sample of pp collisions at a centre-of-mass energy of 7TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 5.3fb−1. The measured ratio is B(B0s→J/ψf0)B(f0→π+π−)B(B0s→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. | en_US |
