Abstract
We discuss the observability at LHC or SSC of anomalous 3-boson and 4-boson couplings generated by the SU(2)c preserving operatorO w . We compute the invariant mass distribution of vector boson pair production viaq\(\bar q\) annihilation and via boson-boson fusion, for all possible channels. both these mechanisms are found to give comparable contributions for SSC and LHC, irrespective of whetherO w exists or not. We find that the channelsWZ andWγ are particularly suitable for studying whetherO w really appears in nature, and conclude that an upper limit on the strength of such an interaction which is better than |λ W |<0.01, should be achievable. This will make a considerable improvement as compared to the indirect limits presently available from LEP1 (|λ W |<0(1)), and expected from LEP2 (|λ W |<0(0.1)).
