We report a measurement of the differential cross section for W boson produ
ction as a function of its transverse momentum in proton-antiproton collisi
ons at roots = 1.8 TeV The data were collected by the DO experiment at the
Fermilab Tevatron Collider during 1994-1995 and correspond to an integrated
luminosity of 85 pb(-1). The results are in good agreement with quantum ch
romodynamics over the entire range of transverse momentum. (C) 2001 Elsevie
