Abstract:

Prototypes of the FERMI system have been used to read out a prototype of the ATLAS hadron calorimeter in a beam test at the CERN SPS. The FERMI read-out system, using a compressor and a sampling ADC, is compared to a standard charge integrating read-out by measuring the energy resolution of the calorimeter separately with the two systems on the same events. Signal processing techniques have been designed to optimize the treatment of FERMI data. The resulting energy resolution is better than the one obtained with the standard read-out. © 1998 Elsevier Science B.V. All rights reserved.

Abstract:

We report a measurement of the W boson mass based on an integrated luminosity of 82pb-1 from pp¯ collisions at √s = 1.8 TeV recorded in 1994-1995 by the D0 detector at the Fermilab Tevatron. We identify W bosons by their decays to ev and extract the mass by fitting the transverse mass spectrum from 28 323 W boson candidates. A sample of 3563 dielectron events, mostly due to Z → ee decays, constrains models of W boson production and the detector. We measure MW = 80.44 ± 0.10(stat) ± 0.07(syst) GeV. By combining this measurement with our result form the 1992-1993 data set, we obtain MW = 80.43 ± 0.11 GeV. © 1998 The American Physical Society.

Abstract:

A measurement of the mass of the [Formula Presented] boson is presented which is based on a sample of 5982 [Formula Presented] decays observed in [Formula Presented] collisions at [Formula Presented] TeV with the D detector during the 1992–1993 run. From a fit to the transverse mass spectrum, combined with measurements of the [Formula Presented] boson mass, the [Formula Presented] boson mass is measured to be [Formula Presented] Detailed discussions of the determination of the absolute energy scale, the measured efficiencies, and all systematic uncertainties are presented. © 1998 The American Physical Society.

Abstract:

We determine the top quark mass [Formula Presented] using [Formula Presented] pairs produced in the DØ detector by [Formula Presented] [Formula Presented] collisions in a [Formula Presented] exposure at the Fermilab Tevatron. We make a two constraint fit to [Formula Presented] in [Formula Presented] final states with one W boson decaying to [Formula Presented] and the other to [Formula Presented] or [Formula Presented] Likelihood fits to the data yield [Formula Presented] When this result is combined with an analysis of events in which both W bosons decay into leptons, we obtain [Formula Presented] An alternate analysis, using three constraint fits to fixed top quark masses, gives [Formula Presented] consistent with the above result. Studies of kinematic distributions of the top quark candidates are also presented. 14.65.Ha, 13.85.Ni, 13.85.Qk. © 1998 The American Physical Society.

Abstract:

The results of a search for W boson pair production in pp collisions at √s= 1.8 TeV with subsequent decay to eμ, ee, and μμ channels are presented. Five candidate events are observed with an expected background of 3.1 ±0.4 events for an integrated luminosity of approximately 97 pb-1. Limits on the anomalous couplings are obtained from a maximum likelihood fit of the ET spectra of the leptons in the candidate events. Assuming identical WWγ and WWZ couplings, the 95% C.L. limits are -0.62<Δκ<0.77 (X. = 0) and -0.53<λ <0.56 (Δκ=0) for a form factor scale Λ= 1.5 TeV. © 1998 The American Physical Society.
