Abstract:

In a preliminary version of the NA48 experiment at the CERN SPS, in which an iron-scintillator sandwich calorimeter was used as a photon detector, the ratio of KL → πμνγ and KL → πμν decays was measured. The branching ratio BR(KL → πμνγ,E*γ ≥30 MeV)/(KL → πμν) is found to be (2.08 ± 0.17+0.16-0.21) × 10-3, where the first error is statistical and the second systematic. The result is in agreement with theoretical predictions. © 1998 Elsevier Science B.V.

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.
