| Özet |
| The ratio of the production cross sections times branching fractions (σ (B±c) B (B±c→ J/ψπ±))/(σ (B±) B (B±→ J/ψK±)) is studied in proton-proton collisions at a center-of-mass energy of 7 TeV with the CMS detector at the LHC. The kinematic region investigated requires B± c and B±mesons with transverse momentum pT> 15 GeV and rapidity| y|< 1.6. The data sample corresponds to an integrated luminosity of 5.1 fb− 1. The ratio is determined to be [0.48±0.05 (stat)±0.03 (syst)±0.05 (τBc)]%. The B±c→ J/ψπ±π±π∓ decay is also observed in the same data sample. Using a model-independent method developed to measure the efficiency given the presence of resonant behaviour in the three-pion system, the ratio of the branching fractions B (B± c→ J/ψπ±π±π∓)/B (B±c→ J/ψπ±) is measured to be 2.55±0.80 (stat)±0.33 (syst)+ 0.04− 0.01 (τBc), consistent with the previous LHCb result. |
