摘　　要：通过Top夸克衰变,在最小超对称标准模型下,在强子对撞机上相继讨论了寻找轻、重带电Higgs玻色子的前景.结果表明:在LHC上,在mH+≥140 GeV及tanβ≤1条件下,三体衰变道提供了质量较轻的荷电Higgs玻色子的可观测信号;而对于质量较重的荷电Higgs玻色子,在tanβ较大区域内,H±→τv是可观测道.In the Minimal Supersymmetric Standard Model, we study the prospects of a relatively light charged Higgs boson search via top quark decay and then a heavy charged Higgs boson search at hadron colliders. It is shown that ： the three -body decay channel provides a visible signature for a light charged Higgs boson search under mH＋≥140GeV and tan β≤1 circumstances while the feasible channels for heavy charged Higgs boson search is H^x→τv channel in large tan β region at LHC.
