CSIC ORCID; Aaltonen, T. | Fecha de publicación: | 1-may-2010 | Editor: | American Physical Society | Citación: | Physical Review - Section D - Particles and Fields 81 (9): 092002 (2010) | Resumen: | We present a measurement of the top-quark pair-production cross section in p (p) over bar collisions at root s = 1.96 TeV using a data sample corresponding to 1.7 fb(-1) of integrated luminosity collected with the Collider Detector at Fermilab. We reconstruct t (t) over bar events in the lepton + jets channel, consisting of e nu + jets and mu nu + jets final states. The dominant background is the production of W bosons in association with multiple jets. To suppress this background, we identify electrons from the semileptonic decay of heavy-flavor jets ("soft electron tags''). From a sample of 2196 candidate events, we obtain 120 tagged events with a background expectation of 51 +/- 3 events, corresponding to a cross section of sigma(t (t) over bar) = 7.8 +/- 2.4(stat) +/- 1.6(syst) +/- 0.5(lumi) pb. We assume a top-quark mass of 175 GeV/c(2). This is the first measurement of the t (t) over bar cross section with soft electron tags in run II of the Tevatron. | Descripción: | 18 páginas, 15 figuras, 8 tablas.-- CDF Collaboration: et al. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevD.81.092002 | URI: | http://hdl.handle.net/10261/28091 | DOI: | 10.1103/PhysRevD.81.092002 | ISSN: | 1550-7998 |
