These data made hadronic open-charm decays of B mesons (B(s) -> pi D(s)), where the D meson decays into fully hadronic final states, accessible for this measurement. Production fraction ratios as functions of B meson transverse momentum (pT) and rapidity (y) are measured using the open-charm decays in the kinematic range of 8 < pT < 60 GeV and |y| < 2.25. In addition, the same data are used to measure the relative production fraction ratios on the charmonium decay channels (B(s) -> X J/psi with X being K, K*0(892), phi(102) mesons) with the J/psi meson decaying into a pair of muons. These measurements are normalized in situ to the measured yields in the open-charm channels, thus allowing for the first time to extract the production fractions in charmonium channels directly with an absolute normalization. These results also improve several world-average values of the ratios of branching fractions of B meson decays to charmonium and open-charm states. Finally, we test isospin invariance in B meson production in proton-proton collisions, and observe no significant deviation from isospin invariance within the experimental uncertainties.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t1","@type":"Dataset","description":"The invariant mass distribution of $B^+$ candidates, corrected using the $D^0$ meson mass, is shown for $13 < p_{T} <...","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t2","@type":"Dataset","description":"The invariant mass distribution of $B^0$ candidates, corrected using the $D^-$ meson mass, is shown for $18 < p_{T} <...","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t3","@type":"Dataset","description":"The invariant mass distribution of $B_s^{0}$ candidates, corrected using the $D^-_{s}$ meson mass, is shown for $23 < p_{T} <...","name":"Figure 2c"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t4","@type":"Dataset","description":"The invariant mass distribution of $B^+$ candidates is shown for $14 < p_{T} < 15$ GeV along with the corresponding...","name":"Figure 3a"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t5","@type":"Dataset","description":"The invariant mass distribution of $B^0$ candidates is shown for $15 < p_{T} < 16$ GeV along with the corresponding...","name":"Figure 3b"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t6","@type":"Dataset","description":"The invariant mass distribution of $B^0_{s}$ candidates is shown for $16 < p_{T} < 18$ GeV along with the corresponding...","name":"Figure 3c"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t7","@type":"Dataset","description":"The invariant mass distribution of $B^+$ candidates is shown for $13 < p_{T} < 18$ GeV along with the corresponding...","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t8","@type":"Dataset","description":"The invariant mass distribution of $B^0$ candidates is shown for $18 < p_{T} < 23$ GeV along with the corresponding...","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t9","@type":"Dataset","description":"The invariant mass distribution of $B^0_{s}$ candidates is shown for $23 < p_{T} < 28$ GeV along with the corresponding...","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.158357.v1/t10","@type":"Dataset","description":"Measured $f_s/f_d$ as a function of $p_T$ using open-charm channels.
