Abstract

We report a search for the

W

boson via the production process

ν_{μ} + Z \to W^{+} + μ^{-} + Z

and decay process

W^{+} \to μ^{+} + ν_{μ}

. We have set a firm lower bound on the mass of the

W

boson as a function of the branching fraction into leptons [

B = \frac{(W \to l + ν)}{(W \to all)}

]. For example, we have determined that

M_{W} > 4.4

GeV/

c^{2}

(90% confidence limit) for

B = 0.5

.
