Measurement of the cross section for tt̄ production in pp̄ collisions using the kinematics of lepton+jets events
Physical Review D Particles Fields Gravitation and Cosmology 72:5 (2005)
Abstract:
We present a measurement of the top pair production cross section in pp̄ collisions at s=1.96TeV. We collect a data sample with an integrated luminosity of 194±11pb-1 with the CDF II detector at the Fermilab Tevatron. We use an artificial neural network technique to discriminate between top pair production and background processes in a sample of 519 lepton+jets events, which have one isolated energetic charged lepton, large missing transverse energy and at least three energetic jets. We measure the top pair production cross section to be σtt̄=6.6±1.1±1.5pb, where the first uncertainty is statistical and the second is systematic. © 2005 The American Physical Society.Search for first-generation scalar leptoquarks in pp̄ collisions at s=1.96 TeV
