We report on searches for a compositeness signature of quarks and leptons in the di-fermion (di-leptons and di-jets) channels using data collected by the D0 detector at the Fermilab Tevatron. We set model-dependent lower limits at the 95% condence level on the compositeness scale of for constructive and destructive interference between the Drell-Yan (DY) amplitude and the contact interaction for various quark and lepton chiralities.
