| 英文摘要 | A measurement of b-hadron pair production is presented, based on a data set corresponding to an integrated luminosity of 11.4 fb(-1) of proton-proton collisions recorded at root s = 8tev with the atlas detector at the lhc. events are selected in which a b-hadron is reconstructed in a decay channel containing j = psi -> mu mu, and a second b-hadron is reconstructed in a decay channel containing a muon. results are presented in a fiducial volume de fined by kinematic requirements on three muons based on those used in the analysis. the fiducial cross section is measured to be 17.7 +/- 0.1(stat.) +/- 2.0(syst.) nb. a number of normalised differential cross sections are also measured, and compared to predictions from the pythia8, herwig++, madgraph5_amc@nlo+pythia8 and sherpa event generators, providing new constraints on heavy flavour production. |
