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.
