Measurement of the ttbar Production Cross Section in ppbar Collisions at sqrts=1.96 TeV using Lepton + Jets Events with Secondary Vertex b-tagging
CDF Collaboration
Abstract
We present a measurement of the ttbar production cross section using events with one charged lepton and jets from ppbar 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 ttbar production cross section of 5.6+1.2-1.1 (stat.) +0.90.6 (syst.) pb.
