Charged and pseudoscalar Higgs boson production at a muon collider - art. no. 071702

We consider single charged Higgs (H+/-) and pseudoscalar Higgs (A(0)) boson production in association with a gauge boson at mu(+)mu(-) colliders. We f ind that the tree-level t-channel and s-channel contributions to mu(+)mu(-) -->H+/- W+/-, A(0)Z are enhanced for large values of tan beta, allowing siz able cross sections whose analogies at e(+)e(-) colliders would be very sma ll. These processes provide attractive new ways of producing such particles at mu(+)mu(-). colliders and are superior to the conventional methods in r egions of parameter space.
