Abstract:

Charge asymmetry has been measured using 19 039 W decays recorded by the Collider Detector at Fermilab during the 1992-93 run of the Tevatron Collider. The asymmetry is sensitive to the ratio of d and u quark distributions to x<0.01 at Q2MW2, where nonperturbative effects are minimal. It is found that of the two current sets of parton distributions, those of Martin, Roberts, and Stirling are favored over the sets most recently produced by the CTEQ Collaboration. The W asymmetry data provide stronger constraints on du ratio than the recent measurements of F2μnF2μp which are limited by uncertainties originating from deuteron corrections. © 1995 The American Physical Society.

Abstract:

This Letter describes a direct measurement of the W boson decay width, Γ(W), using the high-mass tail of the transverse mass spectrum of W→eν decays recorded by the Collider Detector at Fermilab. We findΓ(W)=2.11±0.28(stat)±0.16(syst) GeV and compare this direct measurement with indirect means of obtaining the width. © 1995 The American Physical Society.
