Abstract

We have determined

m_{W}

=79.91±0.39 GeV/

c^{2}

from an analysis of W→eν and W→μν data from the Collider Detector at Fermilab in p¯p collisions at a c.m. energy of √s =1.8 TeV. This result, together with the world-average Z mass, determines the weak mixing angle to be

\sin^{2}

θ_{W}

=0.232±0.008. Bounds on the top-quark mass are discussed.
