In the general two Higgs doublet model with flavor changing neutral Higgs couplings, neutral Higgs bosons may decay dominantly via tc̄ or t̄c final states. At the linear collider, e+e- → h0A0 or H0A0 production processes may result in bb̄tc̄, W+W- tc̄ or ttc̄c̄ (or t̄t̄cc) final states. The process γγ → h0, A0 → tc̄ is also promising, but e+e- → (h0, H0)Z0 → tc̄Z0 is relatively suppressed. The possibility of observing like sign lepton pairs, usually the hallmark for neutral meson mixing, is quite interesting since T0 mesons do not even form.
