摘要: | In the general two Higgs doublet model with flavor changing neutral Higgs couplings, neutral Higgs bosons may decay dominantly via <t(c)over bar> or <(t)over bar c> final states. At the linear collider, e(+)e(-) --> h(0)A(0) or H(0)A(0) production processes may result in <b(b)over bar t(c)over bar>, W+W- t (c) over bar or tt (c) over bar (c) over bar (or (t) over bar (t) over bar cc) final states. The process yy --> h(0), A(0) --> t (c) over bar is also promising, but e(+)e(-) --> (h(0), H-0)Z(0) --> <t(c)over bar Z(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. |
