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 \to e ν

decays recorded by the Collider Detector at Fermilab. We find

Γ (W) = 2.11 \pm 0.28 (stat) \pm 0.16 (syst)

GeV and compare this direct measurement with indirect means of obtaining the width.
