TRIPLET HIGGS BOSONS AT E(+)E(-) COLLIDERS

We investigate the possibility of probing the triplet Higgs boson sect or via single charged Higgs production in the process e(+)e(-) --> H()l nu(l), at high energy electron-positron colliders, using the tree l evel H(+)W(-)Z coupling which is a unique feature of such models. We f ind that even LEP-200 can give nontrivial information up to M(H+/-) si milar or equal to 120 GeV if the doublet-triplet mixing is not restric ted by the current value of the rho parameter. Further we point out th at in such models, the 4-body, tree level decay H+ --> WZ* --> 4 ferm ions dominates and hence provides a very clean signal. At NLC the disc overy range for the charged Higgs in triplet models via this process i s similar to 400 GeV.
