Resumo: | This paper reports a measurement of the W+b-jets (W+b+X and W+$b\bar{b}$ +X) production cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC. These results are based on data corresponding to an integrated luminosity of 4.6 fb$^{-1}$, collected with the ATLAS detector. Cross-sections are presented as a function of jet multiplicity and of the transverse momentum of the leading b-jet for both the muon and electron decay modes of the W boson. The W+b-jets cross-section, corrected for all known detector eects, is quoted in a limited kinematic range. Combining the muon and electron channels, the ducial cross-section for W+b-jets is measured to be 7.1 $\pm$ 0.5 (stat) $\pm$ 1.4 (syst) pb, consistent with the next-to-leading order QCD prediction, corrected for non-perturbative and double-parton interactions (DPI) contributions, of 4.7 $\pm$ 0.09 (stat) $^{+0.60}_{-0.49}$ (scale) $\pm$ 0.06 (PDF) $\pm$ 0.16 (non-pert) $^{+0.52}_{-0.38}$ (DPI) pb. |
