We present a search for anomalous semileptonic decays of heavy
flavor hadrons produced in association with a W boson, in proton-antiproton
collisions at s**(1/2) = 1.96 TeV. We use 162 pb-1 of data collected with
the CDF II detector at the Fermilab Tevatron Collider. We select events
with one W boson and at least one jet with an identified secondary vertex.
In the jets with a secondary vertex we look for a semileptonic decay to a
muon. We compare the number of jets with both a secondary vertex and a
semileptonic decay, and the kinematic properties of these jets, with the
standard model expectation, and we set limits on the production cross
section of a B-like hadron with an anomalously high semileptonic branching
ratio.
