In the general two Higgs doublet model with flavor changing neutral Higgs couplings, neutral Higgs bosons may decay dominantly via tc or tc final states. At the linear collider, e + e - → h 0 A 0 or H 0 A 0 production processes may result inbbtc ,W + W - tc or ttcc (or ttcc) final states. The process γγ → h 0 , A 0 → tc is also promising, bute + e - → (h 0 , H 0 Z 0 →tcZ 0 is relatively suppressed. The possibility of observing like sign lepton pairs, usually the hallmark for neutral meson mixing, is quite interesting since T 0 mesons do not even form.
