Limits on 3 boson vertex parameters from LEP200

LEP will be operating at cm energies above W pair threshold from 1996. The process e⁺e⁻ → W⁺W⁻ will provide a unique opportunity to test some important aspects of the Standard Model. The methodology of studying this process has been reviewed in this report. The study of the process will probe at the triple vector boson coupling. The sensitivity to anomalous coupling of W boson has been discussed in detail.
