Measuring transversity densities in singly polarized hadron-hadron and lepton-hadron collisions
We show how the transverse polarization of a quark initiating a jet can be
probed by the azimuthal distribution of two hadrons (of large ) in the jet.
This permits a twist 2 asymmetry in hard processes when only one of the initial
particles is polarized transversely. Applications to hadron-hadron and
lepton-hadron scattering are discussed.Comment: 16 pages, LaTeX + EPSF, 2 postscript figures. PSU/TH/10
Measurement of the Boson Mass
A measurement of the mass of the boson is presented based on a sample of
5982 decays observed in collisions at
= 1.8~TeV with the D\O\ detector during the 1992--1993 run. From a
fit to the transverse mass spectrum, combined with measurements of the
boson mass, the boson mass is measured to be .Comment: 12 pages, LaTex, style Revtex, including 3 postscript figures

Measurement of the Shape of the Transverse Momentum Distribution of W Bosons Produced in pbarp Collisions at sqrt(s)= 1.8 TeV
The shape of the transverse momentum distribution of W bosons (p_T(W))
produced in pbarp collisions at sqrt(s)= 1.8 TeV is measured with the DO
detector at Fermilab. The result is compared to QCD perturbative and
resummation calculations over the p_T(W) range from 0-200 GeV/c. The shape of
the distribution is consistent with the theoretical prediction.Comment: 11 pages, 3 figure
Determination of the Mass of the W Boson Using the D0 Detector at the Tevatron
A measurement of the mass of the W boson is presented which is based on a
sample of 5982 W -> e nu decays observed in pbar-p collisions at sqrt(s) = 1.8
TeV with the D0 detector during the 1992-1993 run. From a fit to the transverse
mass spectrum, combined with measurements of the Z boson mass, the W boson mass
is measured to be M_W = 80.350+-0.140(stat)+-0.165(sys)+-0.160(scale) GeV/c^2.
Detailed discussions of the determination of the absolute energy scale, the
measured efficiencies, and all systematic uncertainties are presented.Comment: 152 pages, 51 figures in 76 files 2 latex file
