Many theories of new physics predict the existence of new particles decaying to leptons and hadronic jets, including leptoquarks of grand unified theories, heavy neutrinos and right-handed W R bosons of left-right symmetric extensions of the standard model, heavy Majorana neutrinos of see-saw mechanism, and scalar quarks in supersymmetric theories that violate R-parity. The results of searches for these particles, in final states including jets, electrons, muons, and tau leptons, are reported.

Based on good agreement between the data and the standard model expectations, the data are used to determine limits on new particle production at the 95% confidence level.
