Signatures of Higgs-Triplet Representations at Tev--e+e- Colliders

We investigate the potential of future TeV linear e^+e^- colliders to observe singly-charged Higgs bosons ($H^{\pm }$) via the coupling $H^{\pm }{W}^{\mp }Z$, which would signal the existence of exotic Higgs representations. In the context of a Higgs-triplet model compatible with the electroweak oblique parameters, we estimate the cross section for pro- ducing charged Higgs-triplet bosons that couple predominantly to $W$ and $Z$ bosons in 0.5–2 TeV-$e^{+}{e}^{-}$ colliders. The principal backgrounds are evaluated and the viability of the signal is discussed and illustrated.
