Searches for Compositeness at the Tevatron
  Quark-quark and quark-lepton searches for compositenss at the Fermilab Tevatron are summarized. These are of the contact-interaction variety where sqrt(s-hat) < the hypothesized mass scales, Lambda. Tevatron experiments limit a variety of compositeness phenomena in the range from 1.9 to 8.3 TeV. These limits result from measurements of: the Ht spectrum (D0), dijet mass (D0), dijet angular distribution (CDF, D0), drell-yan production (CDF, D0), and the Neutral Current to Charged Current ratio (CCFR/NuTeV).
