- Abstract
- The production of a Z boson, decaying into two leptons and produced in association with one or more b jets, is studied using proton-proton collisions delivered by the LHC at a centre-of- mass energy of 7 TeV and marc:recorded by the CMS detector, with a data sample collected in 2011 and corresponding to an integrated luminosity of 5 fb-1. Cross sections for the Z( ll )+b-jets process (where ll = ee or mm ) are measured for Z bosons produced in association with exactly one or at least two b jets. The cross section ratio for a Z boson produced with any number of b-jets relative to a Z boson produced with any number of jets is also measured. These cross sections are compared with different predictions. Kinematic properties of the reconstructed particles are compared with the predictions from the MADGRAPH 5.1.1.0 event generator, interfaced with PYTHIA 6.424 parton shower simulation.
