摘要：

研究了通过生产过程$e^{-}e^{+} \ra H^{+}H^{-} \ra τ^{+}ντ\barν$的荷电Higgs现象和在未来直线对撞机上的探测机会。两个带电的希格斯玻色子被认为是衰变到$τν$和强子衰变的$τ$轻子进行了分析，考虑到自旋和运动学的影响，使用适当的模拟的$τ$轻子衰变。结果表明，在MSSM框架内，与\tanb = 10，宽范围的带电希格斯质量将有可检测的信号超出$5σ$的统计意义在线性对撞机与$\sqrt{s} = 500$和1000 GeV。

英文摘要：

Charged Higgs phenomenology and detection chance at future linear colliders through the production process $e^{-}e^{+} \ra H^{+}H^{-} \ra τ^{+}ντ\barν$ is studied. Both charged Higgs bosons are considered to decay to $τν$ and the hadronic decay of $τ$ leptons is analyzed taking into account spin and kinematics effects using a proper simulation of the $τ$ lepton decay. It is shown that within the MSSM framework, with \tanb = 10, a wide range of charged Higgs masses would have detectable signal beyond the $5σ$ statistical significance at linear colliders with $\sqrt{s} = 500$ and 1000 GeV.
