Query: Search for techniparticles in e +jets events at D0   We search for the technicolor process ppbar -> rho_T/omega_T ->W+pi_T in
events containing one electron and two jets, in data corresponding to an
integrated luminosity of 390 pb-1, recorded by the D0 experiment at the
Fermilab Tevatron. Technicolor predicts that technipions, pi_T, decay
dominantly into b-bbar, b-cbar, or bbar-c, 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_T vs. rho_T mass plane for a given set of
model parameters.
