Same Language Subtitling (SLS) refers to the idea of subtitling motion media programs in the same language and script associated with the audio track. This apparently small change in certain popular cultural programming contexts on television and cinema, especially, film songs, has shown enormous promise for literacy skill improvement among neo-literate and(More)
We search for the technicolor process pp-->rhoT/omegaT-->WpiT in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb(-1), recorded by the D0 experiment at the Fermilab Tevatron. Technicolor predicts that technipions pi(T) decay dominantly into bb, bc, or bc, depending on their charge. In these events b(More)
The standard model of particle physics contains parameters--such as particle masses--whose origins are still unknown and which cannot be predicted, but whose values are constrained through their interactions. In particular, the masses of the top quark (M(t)) and W boson (M(W)) constrain the mass of the long-hypothesized, but thus far not observed, Higgs(More)
A search for associated production of charginos and neutralinos is performed using data recorded with the D0 detector at a pp center-of-mass energy of 1.96 TeV at the Fermilab Tevatron Collider. This analysis considers final states with missing transverse energy and three charged leptons, of which at least two are electrons or muons. No evidence for(More)
We present the first experimental discrimination between the 2e/3 and 4e/3 top quark electric charge scenarios, using top quark pairs (tt) produced in pp collisions at (square root) s = 1.96 TeV by the Fermilab Tevatron Collider. We use 370 pb;{-1} of data collected by the D0 experiment and select events with at least one high transverse momentum electron(More)
We describe QUAERO, a method that (i) enables the automatic optimization of searches for physics beyond the standard model, and (ii) provides a mechanism for making high energy collider data generally available. We apply QUAERO to searches for standard model WW, ZZ, and t t macro production, to searches for these objects produced through a new heavy(More)
We report the first direct search for the Kaluza-Klein (KK) modes of Randall-Sundrum gravitons using dielectron, dimuon, and diphoton events observed with the D0 detector operating at the Fermilab Tevatron pp(-) Collider at sqrt[s]=1.96 TeV. No evidence for resonant production of gravitons has been found in the data corresponding to an integrated luminosity(More)
We have measured the W boson mass using the DØ detector and a data sample of 82 pb Ϫ1 from the Fermilab Tevatron collider. This measurement uses W→e␯ decays, where the electron is close to a boundary of a central electromagnetic calorimeter module. Such ''edge'' electrons have not been used in any previous DØ analysis, and represent a 14% increase in the W(More)
Based on 85 pb Ϫ1 data of pp ¯ collisions at ͱsϭ1.8 TeV collected using the DØ detector at Fermilab during the 1994 –1995 run of the Tevatron, we present a direct measurement of the total decay width of the W boson ⌫ W. The width is determined from the transverse mass spectrum in the W→eϩ␯ e decay channel and found to be ⌫ W ϭ2.23 Ϫ0.14 ϩ0.15(More)
We search for the production of single top quarks via flavor-changing-neutral-current couplings of a gluon to the top quark and a charm (c) or up (u) quark. We analyze 230 pb{-1} of lepton+jets data from pp[over] collisions at a center of mass energy of 1.96 TeV collected by the D0 detector at the Fermilab Tevatron Collider. We observe no significant(More)
