Search for techniparticles in e+jets events at D0
2007
The authors search for the
technicolorprocess ppbar -> rho{sub T}/omega{sub T} ->W+pi{sub T} in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb-1, recorded by the
D0 experimentat the
Fermilab
Tevatron.
Technicolorpredicts that technipions, pi{sub 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{sub T} vs. rho{sub T} mass plane for a given set of model parameters.
