The data used correspond to an integrated luminosity of 4.2fb−1 . 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 η – ϕ plane of ΔR=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 dijet invariant mass, dijet transverse momentum, boost of the dijet system, and the rapidity difference, azimuthal angle and angular distance between the b-jets.
