The ratio of the production cross sections times branching fractions $\\sigma(B_c^{\\pm})B(B_c^{\\pm} \\to J/\\psi \\pi^{\\pm}) /((\\sigma(B^{\\pm}) B(B^{\\pm} \\to J/\\psi K^{\\pm}))$ 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 $B_c^{\\pm}$ and $B^{\\pm}$ mesons with transverse momentum $p_T$ > 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 $\\pm$ 0.05(stat) $\\pm$ 0.03(syst) $\\pm$ 0.05 ($\\tau_{Bc})$]% . The $B_c^{\\pm} \\to J/\\psi \\pi^{\\pm} \\pi^{\\pm} \\pi^{\\mp}$ 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 $B(B_c^{\\pm} \\to  J/\\psi \\pi^{\\pm} \\pi^{\\pm} \\pi^{\\mp})/B(B_c^{\\pm} \\to J/\\psi \\pi^{\\pm})$ is measured to be 2.55 $\\pm$ 0.80(stat) $\\pm$ 0.33(syst) $\\mathrm{^{+ 0.04}_{-0.01} }(\\tau_{Bc}$), consistent with the previous LHCb result.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.39386.v1/t1","@type":"Dataset","description":"The ratio of the production cross sections times branching fractions of $B_c^\\pm\\to J/\\psi\\pi^\\pm$ and $B^\\pm\\to J/\\psi K^\\pm$ is measured in...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.39386.v1/t2","@type":"Dataset","description":"To determine the systematic uncertainty in the ratio of branching fractions associated with the uncertainty in the $B_c^\\pm$ lifetime, the...","name":"Table 2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1323075?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/39386"}],"inLanguage":"en","name":"Measurement of the ratio B(Bc+/- to J/psi pi+/- pi+/- pi-/+)/B(Bc+/- to J/psi pi+/-) and the production cross sections times branching fractions of Bc+/- to J/psi pi+/- and B+/- to J/psi K+/- in pp collisions at sqrt(s) = 7 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1323075?version=1","version":1}
