• Аннотация: Measurements of the cross-section for producing \bquark quarks in the reaction pp→bb¯¯X are reported in 7 and 13 TeV collisions at the LHC as a function of the pseudorapidity η in the range 2<η<5 covered by the acceptance of the LHCb experiment. The measurements are done using semileptonic decays of b-flavored hadrons decaying into a ground-state charmed hadron in association with a muon. The cross-sections in the covered η range are 72.0±0.3±6.8μb and 154.3±1.5±14.3μb for 7 and 13 TeV. The ratio is 2.14±0.02±0.13, where the quoted uncertainties are statistical and systematic, respectively. The agreement with theoretical expectation is good at 7 TeV, but differs somewhat at 13 TeV. The measured ratio of cross-sections is larger at lower η than the model prediction.

 [1] Measurement of the b-quark production cross-section in 7 and 13 tev pp collisions / А. В. Бережной, И. В. Горелов, А. Д. Козачук et al. // Physical Review D. — 2017. — Vol. 118, no. 5. — P. 052002. Measurements of the cross-section for producing quarks in the reaction pp→bb¯¯X are reported in 7 and 13 TeV collisions at the LHC as a function of the pseudorapidity η in the range 2<η<5 covered by the acceptance of the LHCb experiment. The measurements are done using semileptonic decays of b-flavored hadrons decaying into a ground-state charmed hadron in association with a muon. The cross-sections in the covered η range are 72.0±0.3±6.8μb and 154.3±1.5±14.3μb for 7 and 13 TeV. The ratio is 2.14±0.02±0.13, where the quoted uncertainties are statistical and systematic, respectively. The agreement with theoretical expectation is good at 7 TeV, but differs somewhat at 13 TeV.
