abstract = {A measurement of the top quark pair-production cross section in the lepton þ jets decay channel is
presented. It is based on 4.6 fb−1 of
ffiffiffisp ¼ 7 TeV pp collision data collected during 2011 by the ATLAS
experiment at the CERN Large Hadron Collider. A three-class, multidimensional event classifier based on
support vector machines is used to differentiate t¯t events from backgrounds. The t¯t production cross section
is found to be σt¯t ¼ 168.5   0.7ðstatÞ þ6.2
−5.9 ðsystÞ þ3.4
−3.2 ðlumiÞ pb. The result is consistent with the Standard
Model prediction based on QCD calculations at next-to-next-to-leading ord},
