Resumen:
We search for anomalous production of heavy-flavor quark jets in association with W bosons at the Fermilab Tevatron ppbar Collider in final states in which the heavy-flavor quark content is enhanced by requiring at least one tagged jet in an event. Jets are tagged using one algorithm based on Semileptonic decays of b/c hadrons, and another on their lifetimes. We compare e + jets (164 pb-1) and m + jets (145 pb-1) channels collected with the D0 detector at sqrt(s) = 1.96 TeV to expectations from the standard model and set upper limits on anomalous production of such events.
