Abstract
The associated production of a boson with a jet originating from either a light parton or heavy-flavor quark is studied in the forward region using proton-proton collisions. The analysis uses data corresponding to integrated luminosities of 1.0 and collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, respectively. The bosons are reconstructed using the decay and muons with a transverse momentum, , larger than 20 GeV in the pseudorapidity range . The partons are reconstructed as jets with and . The sum of the muon and jet momenta must satisfy . The fraction of events that originate from beauty and charm quarks is measured, along with the charge asymmetries of the and production cross sections. The ratio of the to production cross sections is also measured using the decay. All results are in agreement with Standard Model predictions.
