Sumario:The preliminary results of charged trilinear gauge boson WWV, V identical to Z/ gamma coupling values presented in this paper were obtained by the four LEP2 experiments ALEPH, DELPHI, L3 and OPAL by analysing the data collected at LEP energies ranging from square root s=183 GeV to square root s=202 GeV. At these energies, significantly above the kinematic threshold for W/sup +/W/sup -/ boson pair production, each of the four experiments collected data equivalent to more than L~500 pb/sup -1/ of integrated luminosity. The estimation of trilinear gauge boson couplings based on this data provides an independent check of the gauge nature of the standard model. (20 refs).
