Resumen

A measurement of b-hadron pair production is presented, based on a dataset corresponding to an integrated luminosity of 11.4 fb−1 of proton–proton collisions recorded at √s = 8 TeV with the ATLAS detector at the LHC. Events are selected in which both a b-hadron → J/ψ(→ µµ) + X and b-hadron → µ + X were identified, and results are presented in a fiducial volume defined 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
