论文摘要
在本文中，在2HDM中分析了在未来的线性校区下作为双Higgs生产（2H）的来源以及在未来的线性壁物的三重HIGGS生产（3H）的过程。这项研究的主要目的是计算和比较未来的线性校友中双重和三重希格斯生产过程中的横截面。产生双重充电的Higgs Boson（$ H^{+} H^{ - } $）以及三重Higgs boson（$ h^{+} h^{ - } h^{ - } h^{0} $），（$ h^{+h^{+} h^{ - } h^{ - } h^h^0} $在两个中心atter ter ter ten teter ten teter ten ten teter ative at in ter int ten ten at per at in ten at in ten at in fiter，将来的线性凸起者型号2HDM和MSSM。可以观察到，对于双电荷Higgs生产过程（H $ {}^{+} $ H $ {}^{ - } $）在两个模型中，结果横截面值几乎相同（在2HDM和MSSM中）。另一方面，在三重希格斯生产过程（$ h^{+} h^{ - } h^{0} $），（$ h^{+} h^{ - } h { - } h {0} $）与MSSM相比，在2HDM中观察到了几个在交叉部门中的增强订单。同样，两种类型的过程，中性的希格斯对生产（$ a^{0} h^{0} $）以及（$ a^{0} h^{0} $）和三个中性higgs生产（$ h^{0} h^{0} h^{0} a^0} a^0} a^0} $） $μ^{+} $$μ^{ - \} $对撞机，用于从500 GEV到3000 GEV的各种质量中心值（0.5 TEV至3 TEV）。观察到中性希格斯对生产的横截面（$ a^{0} h^{0} $）的过程相对较大，比中性希格斯对生产（$ a^{0} h^{0} $）进程。同样，对于中性希格斯三重生产（$ h^{0} h^{0} a^{0} $）在横截面中可以看到增强功能，随着tanß的增加。
In this paper such processes which act as a source of double Higgs production (2H) as well as triple Higgs production (3H) at future linear colliders are analyzed with in 2HDM and its special type-II, MSSM at various center of mass energies. The main aim of this study is to compute and also compare the cross-sections in double and triple Higgs production processes at the future linear colliders. The production of double charged Higgs boson ($H^{+}H^{-}$) as well as triple Higgs boson ($H^{+}H^{-}H^{0}$),($H^{+}H^{-}h^{0}$) are considered for study at two center of mass energies (1.5 TeV and 3 TeV) within two models 2HDM and MSSM at future linear colliders. It is observed that for double charged Higgs production process (H${}^{+}$H${}^{-}$) the resulting cross-section values are almost same in both the models (in 2HDM and MSSM). On the other hand in the case of Triple Higgs production process ($H^{+}H^{-}H^{0}$), ($H^{+}H^{-}h{0}$) several orders of enhancement in cross-sections is observed in 2HDM as compared to MSSM. Similarly two types of processes, neutral Higgs pair production ($A^{0} H^{0}$) as well as ($A^{0} h^{0}$) and triple neutral Higgs production ($h^{0}h^{0}A^{0}$) is analyzed in 2HDM type-I at the future linear $μ^{+}$$μ^{-\ }$ collider for various values of center of mass energies from 500 GeV to 3000 GeV (0.5 TeV to 3 TeV). It is observed that the cross-section for neutral Higgs pair production ($A^{0} h^{0}$) process is comparatively greater than that of neutral Higgs pair production ($A^{0} H^{0}$) process. Similarly for neutral Higgs Triple production ($h^{0}h^{0}A^{0}$) an enhancement is seen in cross-sections with increase of tanß.
