Measurement of the production cross section for <i>W</i> -bosons in association with jets in <i>pp</i> collisions at √s = 7 TeV with the ATLAS detector

This Letter reports on a first measurement of the inclusive <i>W</i> + jets cross section in proton–proton collisions at a centre-of-mass energy of 7 TeV at the LHC, with the ATLAS detector. Cross sections, in both the electron and muon decay modes of the <i>W</i> -boson, are...

Cross sections, in both the electron and muon decay modes of the <i>W</i> -boson, are presented as a function of jet multiplicity and of the transverse momentum of the leading and next-to-leading jets in the event. Measurements are also presented of the ratio of cross sections σ(<i>W</i> + ≥ n)/σ(<i>W</i> + ≥ n − 1) for inclusive jet multiplicities n = 1–4. The results, based on an integrated luminosity of 1.3 pb<sup>−1</sup>, have been corrected for all known detector effects and are quoted in a limited and well-defined range of jet and lepton kinematics. The measured cross sections are compared to particle-level predictions based on perturbative QCD. Next-to- leading order calculations, studied here for n ≤ 2, are found in good agreement with the data. Leading- order multiparton event generators, normalized to the NNLO total cross section, describe the data well for all measured jet multiplicities.La lista completa de autores puede verse en el archivo asociado.Instituto de Física La Plata2011-03-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArticulohttp://purl.org/coar/resource_type/c_6501info:ar-repo/semantics/articuloapplication/pdf325-345http://sedici.unlp.edu.ar/handle/10915/79513enginfo:eu-repo/semantics/altIdentifier/issn/0370-2693info:eu-repo/semantics/altIdentifier/doi/10.1016/j.physletb.2011.03.012info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by/4.0/Creative Commons Attribution 4.0 International (CC BY 4.0)reponame:SEDICI (UNLP)instname:Universidad Nacional de La Platainstacron:UNLP2024-05-08T12:50:44Zoai:sedici.unlp.edu.ar:10915/79513Institucionalhttp://sedici.unlp.edu.ar/Universidad públicaNo correspondehttp://sedici.unlp.edu.ar/oai/snrdalira@sedici.unlp.edu.arArgentinaNo correspondeNo correspondeNo correspondeopendoar:13292024-05-08 12:50:44.68SEDICI (UNLP) - Universidad Nacional de La Platafalse

Measurements are also presented of the ratio of cross sections σ(<i>W</i> + ≥ n)/σ(<i>W</i> + ≥ n − 1) for inclusive jet multiplicities n = 1–4.
