Title: Search for Techniparticles in e+jets Events at D0

Abstract

We search for the technicolor process pp{yields}{rho}{sub T}/{omega}{sub T}{yields}W{pi}{sub T} in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb{sup -1}, recorded by the D0 experiment at the Fermilab Tevatron. Technicolor predicts that technipions {pi}{sub T} decay dominantly into bb, bc, or bc, depending on their charge. In these events b and c quarks are identified by their secondary decay vertices within jets. Two analysis methods based on topological variables are presented. Since no excess above the standard model prediction was found, the result is presented as an exclusion in the {pi}{sub T} vs {rho}{sub T} mass plane for a given set of model parameters.
