Abstract:

The shape of the transverse momentum distribution of W bosons (pWT) produced in pp¯ collisions at √s = 1.8 TeV is measured with the D0 detector at Fermilab. The result is compared with QCD perturbative and resummation calculations over the pWT range from 0 to 200 GeV/c. The shape of the distribution is consistent with the theoretical prediction. © 1998 The American Physical Society.

Abstract:

Photon diffractive dissociation, γp → Xp, has been studied at HERA with the ZEUS detector using ep interactions where the virtuality Q2 of the exchanged photon is smaller than 0.02 GeV2. The squared four-momentum t exchanged at the proton vertex was determined in the range 0.073 < \t\ < 0.40 GeV2 by measuring the scattered proton in the ZEUS Leading Proton Spectrometer. In the photonproton centre-of-mass energy interval 176 < W < 225 GeV and for masses of the dissociated photon system 4 < Mx < 32 GeV, the t distribution has an exponential shape, dN/d\t\ ∝ exp (-b\t\), with a slope parameter b = 6.8 ± 0.9 (stat.) +1.2-1.1 (syst.) GeV-2.

Abstract:

The D0 Collaboration has performed a measurement of the top quark mass mt based on six candidate events for the process tt- → bW+bW-, where the W bosons decay to eν or μν. This sample was collected during an exposure of the D0 detector to an integrated luminosity of 125pb-1 of √ s = 1.8 TeV pp collisions. We obtain mt = 168.4 ± 12.3(stat) ± 3.6(syst) GeV/c2, consistent with the measurement obtained using single-lepton events. Combination of the single-lepton and dilepton results yields mt = 172.0 ± 7.5 GeV/c2. © 1998 The American Physical Society.
