"Table 12" of "Studies of inclusive four-jet production with two b-tagged jets in proton-proton collisions at 7 TeV"

CERN-LHC. Measurements are presented of the cross section for the production of at least four jets, of which at least two originate from b quarks, in proton-proton collisions. Data collected with the CMS detector at the LHC at a center-of-mass energy of 7 TeV are used, corresponding to an integrated luminosity of 3 pb inverse. The cross section is measured as a function of the jet transverse momentum for pT > 20 GeV, and of the jet pseudorapidity for |eta| < 2.4 (b jets), 4.7 (untagged jets). The correlations in azimuthal angle and pT between the jets are also studied. The inclusive cross section is measured to be sigma(pp -> 2 b + 2 j + X) = 69 +- 3 (stat) +- 24 (syst) nb. The eta and pT distributions of the four jets and the correlations between them are well reproduced by event generators that combine perturbative QCD calculations at next-to-leading-order accuracy with contributions from parton showers and multiparton interactions. The four-jet fiducial region is defined as: - at least four jets in the final state in |eta|<4.7 and with pT > 20 GeV. - Two jets are required to contain a bottom quark at a smaller distance than 0.3 in DeltaR.
