Query: Constraints on Electroweak Contact Interactions from LEP and Tevatron
  Data   A complete set of dimension-6 effective contact interactions involving Higgs,
gauge bosons and quarks is studied. Limits on the coefficients of these new
operators are obtained from the experimental values of the $Z$ and $W$ gauge
bosons widths.
