Abstract:
A measurement of the angular correlations between beauty jets produced in pp collisions at a center-of-mass energy of 7 TeV at LHC is presented. A heavy-flavor enriched event sample is selected by a low-transverse-momentum single-muon trigger. Hadronic jets are identified as beauty jets by the presence of nearby high impact parameter tracks. The measured differential di-beauty jet production cross sections, and , are obtained from a sample whose integrated luminosity corresponds to . The visible kinematic phase-space is defined by the requirement of two b-tagged jets with GeV and , with an angular separation of between them, one of the jets has a muon within its decay products with GeV and . The results obtained in data are compared with predictions based on perturbative QCD calculations.Note:
