摘要
We place bounds on anomalous gauge boson couplings from LEP data with particular emphasis on those couplings which do not contribute to Z decays at tree level. We use an effective field theory formalism to compute the one-loop corrections to the Z --> fBARf decay widths resulting from non-standard model three and four gauge boson vertices. We find that the precise measurements at LEP constrain the three gauge boson couplings at a level comparable to that obtainable at LEP II and LHC.
