The analysis uses a data sample corresponding to an integrated luminosity of 36 pb-1and is based on the reconstruction of the final state with one isolated, high transverse-momentum electron or muon and three or more hadronic jets. The kinematic properties of the events are used to separate the tt̄ signal from W+jets and QCD multijet background events. The measured cross section is 173+39                         -32(stat. + syst.) pb, consistent with standard model expectations. © 2011 CERN for the benefit of the CMS collaboration.</dc:description><dc:publisher>Springer New York LLC</dc:publisher><dc:date>2011</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/16004</dc:identifier><dc:identifier>https://doi.org/10.1140/epjc/s10052-011-1721-3</dc:identifier><dc:identifier>1434-6044</dc:identifier><dc:language>en</dc:language><dc:relation>European Physical Journal C</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/16004</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
