Measurement of theW-bosonPTdistribution inp¯pcollisions at √s=1.8 TeV

Using the Collider Detector at Fermilab, the W-boson differential cross section dσ/${\mathit{dP}}_{\mathit{T}}$ is measured using W→eν events in proton-antiproton collisions at √s =1.8 TeV. A next-to-leading-order theoretical calculation agrees well with the data. The cross section (σ) for ${\mathit{P}}_{\mathit{T}}$>50 GeV/c is measured to be 423±58(stat)±108(syst) pb.
