Abstract
We describe a measurement of the ratio of the cross sections times branching fractions of the B+c meson in the decay mode B+c→J/ψμ+ν to the B+ meson in the decay mode B+→J/ψK+ in proton-antiproton collisions at center-of-mass energy √s=1.96 TeV. The measurement is based on the complete CDF Run II data set, which comes from an integrated luminosity of 8.7 fb−1. The ratio of the production cross sections times branching fractions for B+c and B+ mesons with momentum transverse to the beam greater than 6 GeV/c and rapidity magnitude smaller than 0.6 is 0.211±0.012(stat)+0.021−0.020(syst). Using the known B+→J/ψK+ branching fraction, the known B+ production cross section, and a selection of the predicted B+c→J/ψμ+ν branching fractions, the range for the total B+c production cross section is estimated.
