Measurement of the Z/gamma* plus b-jet cross section in pp collisions at root s=7 TeV

Abstract:

The 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 7TeV 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 ℓ ℓ = ee or μ μ) for events with the invariant mass 60 < M ℓ ℓ < 120 GeV, at least one b jet at the hadron level with p...
