ON THE DETERMINATION OF THE TRILINEAR BOSON COUPLINGS IN E(+)E(-)-]L(V)OVER-BAR(L) Q(Q)OVER-BAR' AT LEPII

We present the full tree-order calculation of the process e(+) e(-) --> l ($) over bar nu(l) q ($) over bar q(') including the width effects in a way which is consistent with gauge invariance and high-energy unitarity and which has a natural interpretation within standard perturbation theory. We also include C and P preserving deviations from Standard Model trilinear vector boson couplings. An analysis of the sensitivity of these channels on the trilinear couplings, using well measured angular variables of the four-fermion final state, is also presented.
