"Measurement of the Z/γ*  + b-jet cross section in pp collisions at √s=7 TeV." <i>Journal of High Energy Physics,</i> 2012, no. 126 (2012) Springer: http://dx.doi.org/10.1007/JHEP06(2012)126.https://hdl.handle.net/1911/81004The production of b jets in association with a Z/γ* boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV and recorded by the CMS detector. The inclusive cross section for Z/γ* + b-jet production is measured in a sample corresponding to an integrated luminosity of 2.2 fb−1. The Z/γ* + b-jet cross section with Z/γ* → ℓℓ (where ℓℓ = ee or μμ) for events with the invariant mass 60 < M ℓℓ  < 120 GeV, at least one b jet at the hadron level with p T > 25 GeV and |η| < 2.1, and a separation between the leptons and the jets of ΔR > 0.5 is found to be 5.84±0.08(stat.)±0.72(syst.)+0.25−0.55 (theory) pb. The kinematic properties of the events are also studied and found to be in agreement with the predictions made by the MadGraph event generator with the parton shower and the hadronisation performed by pythia.engJHEP is an open-access journal funded by SCOAP3 and licensed under CC BY 4.0Journal articleHadron-Hadron Scatteringhttp://dx.doi.org/10.1007/JHEP06(2012)126
