The measurements use data corresponding to an integrated luminosity of 34 pb(-1). The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < p(T) < 400 GeV and rapidity in the range vertical bar y vertical bar < 2.1. The b<(b)over bar>-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m(jj) < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured b (b) over bar -dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.", optnote="WOS:000298347800030", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=852), last updated on Fri, 20 Jan 2012 12:19:44 +0000", issn="1434-6044", doi="10.1140/epjc/s10052-011-1846-4", opturl="http://arxiv.org/abs/1109.6833", opturl="https://doi.org/10.1140/epjc/s10052-011-1846-4", archivePrefix="arXiv", eprint="1109.6833", language="English" }
