Title: Measurement of the top-quark mass using missing E{sub T}+jets events with secondary vertex b-tagging at CDF II

Abstract

We present a measurement of the top-quark mass in pp collisions at {radical}(s)=1.96 TeV which uses events with an inclusive signature of missing transverse energy and jets. The event selection is sensitive to tt{yields}W{sup +}bW{sup -}b{yields}l{nu}bqq{sup '}b independent of the lepton flavor and results in a large acceptance for W{yields}{tau}{nu} decays. All-hadronic tt 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{sup -1} of integrated luminosity recorded by the Collider Detector at Fermilab, we measure a top-quark mass m{sub t}=172.3{sub -9.6}{sup +10.8}(stat){+-}10.8(syst) GeV/c{sup 2}. While the uncertainty on m{sub 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{sub t} uncertainty when combined with other existing measurements.
