Abstract

We search for anomalous production of heavy-flavor quark jets in association with W bosons at the Fermilab Tevatron pp¯ 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 (164pb1) and μ+jets (145pb1) channels collected with the D0 detector at s=1.96TeV to expectations from the standard model and set upper limits on anomalous production of such events.
