T. Affolder et al., Measurement of the t(t)over-bar production cross section in p(p)over-bar collisions at root s=1.8 TeV - art. no. 032002, PHYS REV D, 6403(3), 2001, pp. 2002
We update the measurement of the t (t) over bar production cross section us
ing the CDF detector at the Fermilab Tevatron. This measurement uses t (t)
over bar decays to the final states e + nu + jets and mu + nu + jets. We se
arch for b quarks from t decays via secondary-vertex identification or the
identification of semileptonic decays of the b and cascade c quarks. The ba
ckground to the t (t) over bar production is determined primarily through a
Monte Carlo simulation. However, we calibrate the simulation and evaluate
its uncertainty using several independent data samples. For a top quark mas
s of 175 GeV/c(2), we measure sigma (t (t) over bar)-=5.1 +/- 1.5 pb and si
gma (t (t) over bar)=9.2 +/- 4.3 pb using the secondary vertex and the lept
on tagging algorithms, respectively. Finally, we combine these results with
those from other t (t) over bar decay channels and obtain sigma (t (t) ove
r bar)-= 6.5 (+1.7)(-1.4)pb.
