The data used correspond to an integrated luminosity of 4.2 fb(-1). The cross section is measured for events with two identified b-jets with a transverse momentum pT > 20GeV 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 p(T) > 270GeV. 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. The results are compared to different predictions of leading order and next-to-leading order perturbative quantum chromodynamics matrix elements supplemented with models for parton-showers and hadronization.eninfo:eu-repo/semantics/openAccessBOTTOM-QUARK PRODUCTIONP(P)OVER-BAR COLLISIONSHEAVY QUARKSROOT-SArticle2-s2.0-8500369626210.1140/epjc/s10052-016-4521-y28316501Q1WOS:000389893600002
