FLAVOR-CHANGING NEUTRAL SCALAR CURRENTS AT MU(-) COLLIDERS()MU()

The prospect of observing the decay H --> t (c) over bar of a neutral Higgs produced via the s channel and its subsequent decay into t (c) o ver bar is considered at a mu(+)mu(-) collider. In the context of a tw o Higgs doubler model with flavor-changing couplings, it is found that for many values of the model parameters such tree-level flavor changi ng decays will be produced at an observable level. Studies of the heli city of the top will also allow the determination of the relative stre ngths of the flavor-changing couplings, and these may be measured with about 10(3) events.
