摘要:

在两个Higgs双态模型的框架下,我们研究了光子-光子碰撞中的双Higgs产生,作为对Higgs相互作用新动力学的探索。我们分析了中性希格斯玻色子的生产和衰变的融合过程中,$γγ\to S_iS_j$,$S_i=h^0, H^0, A^0$,并表明,$h^0h^0$和$A^0A^0$生产可以提高在该地区的阈值效应$E_{γγ}\approx 2 m_{H\pm}$。当重希格斯粒子$H^0$衰变为两个轻CP偶$h^0$或两个轻CP奇$A^0$标量时,它的共振效应也会在截面增强中发挥作用。我们扫描了双希格斯模型的参数空间,发现了一个很大的参数空间区域,其横截面比标准模型横截面高出两个数量级。我们进一步表明,标准模型实验分析可以用来发现或限制两个Higgs二重态模型参数空间。

英文摘要:

We study double Higgs production in photon-photon collisions as a probe of the new dynamics of Higgs interactions in the framework of two Higgs Doublet Models. We analyze neutral Higgs bosons production and decay in the fusion processes, $γγ\to S_iS_j$, $S_i=h^0, H^0, A^0$, and show that both $h^0h^0$ and $A^0A^0$ production can be enhanced by threshold effects in the region $E_{γγ}\approx 2 m_{H\pm}$. Resonant effects due to the heavy Higgs, $H^0$, can also play a role in the cross section enhancement when it is allowed to decay to two light CP-even $h^0$ or to two light CP-odd $A^0$ scalars. We have scanned the allowed parameter space of the Two Higgs Doublet Model and found a vast region of the parameter space where the cross section is two orders of magnitude above the Standard Model cross section. We further show that the Standard Model experimental analysis can be used to discover or to constraint the two Higgs doublet model parameter space.
