Abstract
We present a search for anomalous semileptonic decays of heavy flavor hadrons produced in association with a boson in proton-antiproton collisions at . We use of data collected with the CDF II detector at the Fermilab Tevatron Collider. We select events with one 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 of plus heavy flavor production and decay. No discrepancy is seen between the observation and the expectation, and we set limits on the production cross section of a -like hadron with an anomalously high semileptonic branching ratio.
