Measurement of the top-quark mass in p(p)over-bar collisions using events with two leptons

Original language description

We present a measurement of the top-quark mass (m(t)) in p (p) over bar collisions at root s = 1.96 TeV using t (t) over bar events with two leptons (ee, e mu, or mu mu) and accompanying jets in 4.3 fb(-1) of data collected with the D0 detector at the Fermilab Tevatron collider. We analyze the kinematically underconstrained dilepton events by integrating over their neutrino rapidity distributions. We reduce the dominant systematic uncertainties from the calibration of jet energy using a correction obtained from t (t) over bar events with a final state of a single lepton plus jets. We also correct jets in simulated events to replicate the quark flavor dependence of the jet response in data. We measure m(t) = 173.7 +/- 2.8 (stat) +/- 1.5 (syst) GeV and combining with our analysis in 1 fb(-1) of preceding data we measure m(t) = 174.0 +/- 2.4 (stat) +/- 1.4 (syst) GeV. Taking into account statistical and systematic correlations, a combination with the D0 matrix element result from both dat
