This analysis is based on data collected by the CMS experiment at the LHC corresponding to an integrated luminosity of 2.3 fb(-1). The measurements are performed in the lepton + jets decay channels with a single muon or electron in the final state. The differential cross sections are presented at particle level, within a phase space close to the experimental acceptance, and at parton level in the full phase space. The results are compared to several standard model predictions.eninfo:eu-repo/semantics/openAccessArticle959WOS:0004006683000012-s2.0-8502005802710.1103/PhysRevD.95.092001Q1Q1
