This paper reports a measurement of the $W+b$-jets \nproduction cross-section in proton-proton collisions at a centre-of-mass energy \nof 7 TeV at the LHC. These results are based on data corresponding to an \nintegrated luminosity of 4.6 fb$^{-1}$, collected with the ATLAS detector. \nCross-sections are presented as a function of jet multiplicity and of the \ntransverse momentum of the leading $b$-jet for both the muon and electron decay \nmodes of the $W$ boson. The $W+b$-jets cross-section, corrected for all known \ndetector effects, is quoted in a limited kinematic range, using jets \nreconstructed with the anti-$k_t$ clustering algorithm with transverse momentum \nabove 25 GeV and rapidity within +- 2.1. Combining the muon and electron \nchannels, the fiducial cross-section for $W+b$-jets is measured to be 7.1 +- 0.5 \n(stat) +- 1.4 (syst) pb, consistent with next-to-leading order QCD calculations \nwithin 1.5 standard deviations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.66629.v2/t1","@type":"Dataset","description":"Measured fiducial $W+b$-jets cross-sections for the combination of the electron and muon channels with statistical and systematic uncertainties and breakdown...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.66629.v2/t2","@type":"Dataset","description":"Breakdown of relative systematic uncertainties per jet multiplicity, and combined across jet bins.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.66629.v2/t3","@type":"Dataset","description":"Measured fiducial $W+b$-jets cross-section in the 1-jet region with statistical and systematic uncertainties in bins of $p_T^{b-jet}$.
