We present the first measurement of the production cross
section of a W boson with a single charm quark (c) in p anti-p collisions
at s**(1/2) = 1.96 TeV, using soft muon tagging of c jets. In a data
sample of ~ 1.8 fb-1, recorded with the CDF II detector at the Fermilab
Tevatron, we select events with W + 1 or 2 jets. We use the charge
correlation between the W and the muon from the semileptonic decay of a
charm hadron to extract the Wc signal. We measure sigma_Wc(p(t)c >
20 GeV/c, |eta_c| < 1.5) x BR(W --> l nu) = 9.8 +/- 3.2 pb, in
agreement with theoretical expectations.
