Measurement of the tt¯ production cross section in pp¯ collisions at √(s)=1.96 TeV using lepton + jets events with secondary vertex b -tagging
Abstract
We present a measurement of the tt¯ production cross section using events with one charged lepton and jets from pp¯ collisions at a center-of-mass energy of 1.96 TeV. In these events, heavy flavor quarks from top quark decay are identified with a secondary vertex tagging algorithm. From 162 pb-1 of data collected by the Collider Detector at Fermilab, a total of 48 candidate events are selected, where 13.5±1.8 events are expected from background contributions. We measure a tt¯ production cross section of 5.6+1.2-1.1(stat.)+0.9-0.6(syst.) pb.
