Abstract

The prospect of observing the flavor changing decay $\\fH\\to t\\bar c$ of a\nneutral Higgs boson produced via $s$-channel and its subsequent decay into\n$t\\bar c$ is considered at a $\\mu^+\\mu^-$ collider. Numerical estimates are\ngiven in the context of a two Higgs doublet model with flavor changing\ncouplings. It is found that for many values of the model parameters such {\\it\ntree-level} flavor changing decays will be produced at an observable level. In\naddition studies of the helicity of the top will allow the determination of the\nrelative strengths of the flavor changing Higgs couplings and these may be\nmeasured with about $10^3$ events.\n
