论文摘要
该研究旨在调查伪凯尔·希格斯玻色子$ a $ a $和中性重型CP的可观察性，甚至在不同基准点上，在I型I 2HDM的框架内，在不同的基准点上也可以观察到。该研究是针对$ e^{ - } e^{+} $碰撞在$ \ sqrt {s} $ = 1000 GEV Mass Energy中心（C.O.M.）的碰撞的情况。 $ a $ a $ h $ in $ e+ e- $碰撞的相关产量以两个不同的渠道进行了完全耐达的最终状态。第一个是$ ah \ to zhh \ to j \ bar {j} b \ bar {b} b \ bar {b} $，而另一个是$ ah \ to b \ bar {b} b \ bar {b bar {b} $。在参数空间$（\tanβ，m_ {a}）$的情况下，中性重的希格斯和伪级希格斯信号的可观察性是可能的，它满足了所有实验性和理论约束。当信号超过$5σ$时，CP ODD和CP甚至Higgs玻色子都可以观察到，这是信号显着性的最终提取值。信号显着性是在不同的集成亮度下计算的。从目前的分析得出的结论是，完全耐足的通道有望在2HDM中搜索和测量中性希格斯玻色子。
The study aims to investigate the observability of pseudoscalar Higgs boson $A$ and neutral heavy CP even Higgs boson $H$, at different benchmark points, in the framework of type-I 2HDM. The study is done for $e^{-}e^{+}$ collisions at $\sqrt{s}$ = 1000 GeV centre of mass energy (c.o.m.) a possible scenario in future lepton collider. The associated production of $A$ and $H$ in $e+ e-$ collisions are investigated in fully hadronic final state in two different channels. The first one is $AH \to ZHH \to j\bar{j} b \bar{b}b\bar{b}$ while the other one is $AH \to b \bar{b}b\bar{b}$. The observability of neutral heavy Higgs and pseudoscalar Higgs signal is possible within the parameter space $ (\tan β, m_{A}) $ which satisfies all experimental and theoretical constraints. The CP odd and CP even Higgs bosons in all scenarios are observable when signal exceeds $ 5σ$, which is the final extracted value of signal significance. The signal significance is calculated at different integrated luminosities. It is concluded from current analysis that fully hadronic channel is promising for search and measurement of the neutral Higgs Bosons in 2HDM.
