ResumenWe present a measurement of the top-quark mass in p(p)over bar collisions at sqrt{s} = 1.96 TeV which uses events with an inclusive signature of missing transverse energy and jets. The event selection is sensitive to t(t)over bar -> W(+)bW(-)(b)over bar -> l nu bqq'(b)over bar independent of the lepton flavor and results in a large acceptance for W -> tau nu decays. All-hadronic t(t)over bar decays and events with identified electrons or muons are vetoed to provide a statistically independent sample with respect to all previous measurements. The top-quark mass is inferred from the distribution of the scalar sum of all jet transverse energies and the missing transverse energy. Using 311 pb(-1) of integrated luminosity recorded by the Collider Detector at Fermilab, we measure a top-quark mass m(t) = 172.3(-9.6)(+10.8)(stat) ± 10.8(syst) GeV/c^2. While the uncertainty on m(t) is larger than that of other measurements, the result is statistically uncorrelated with those of other methods and thus can help to reduce the overall m(t) uncertainty when combined with other existing measurements.
