Measurement of the dijet production cross section for jets containing a b-hadron (b-jets) in proton proton collisions at a centre-of-mass energy of 7 TeV, with 4.2 fb^-1 of data collected by the ATLAS detector in 2011. The cross section is measured for events with two identified b-jets with a transverse momentum pT > 20 GeV and a minimum separation in the eta-phi plane of  Delta R = 0.4. At least one of the jets in the event is required to have pT > 270 GeV. The cross section is measured differentially as a function of the dijet invariant mass, dijet transverse momentum, boost of the dijet system, and of the rapidity difference, azimuthal angle and angular distance between the b-jets. \n\n\n\n\n\nRanges of the variables of the measured differential cross sections:\n\n- m_bb : 50 - 1000 GeV   (mass of the b-bbar di-jet system)\n\n- pT_bb : 0 - 400 GeV    (transverse momentum of the b-bbar di-jet system)\n\n- y_B : 0 - 2.5          (boost of the b-bbar dijet system y_b = (y1+y2)/2 )\n\n- Delta phi : 0 - pi     (azimuthal angle between the two b-jets)  \n\n- Delta R : 0.4 - 4.0  (angular distance between the two b-jets) \n\n- y* : 0 - 1.7           (rapidity difference between the two b-jets y* = |y1 -y2|/2 )\n\n\n\n\n\nCuts defining the fiducial region:\n\n- Leading jet pT > 270 GeV and |eta| < 3.2\n\n- Both b-jets with pT > 20 GeV and |eta| < 2.5\n\n\n- The two b-jets must have an angular separation Delta R > 0.4.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.75316.v1/t1","@type":"Dataset","description":"Results for the m_bb distribution.
