规范-希格斯暗物质的对撞机特征

Collider signatures of the Gauge-Higgs Dark Matter

Kingman Cheung, Jeonghyeon Song

摘要:

最近提出的在Randall-Sundrum弯曲空间中的SO(5)xU(1)规范-Higgs统一模型包含了一个非常有趣的暗物质候选者--希格斯玻色子玻色子。作为五维规范场第五分量的一部分,四维中性希格斯玻色子具有奇H宇称,而其他标准模型粒子在微扰论中具有各阶偶宇称。基于H宇称守恒的WWHH和ZZHH顶点,我们研究了LHC和ILC中与SM W或Z规范玻色子相关的Higgs暗物质产生的对撞机特征。最终态由W或Z玻色子组成,具有大的能量损失。我们发现,信号截面的水平是相当无望的LHC,而我们可能能够识别它在ILC与极化电子束。

英文摘要:

A recently proposed SO(5)xU(1) gauge-Higgs unification model in the Randall-Sundrum warped space contains a very interesting dark matter candidate, the Higgs boson. As a part of the fifth component of a five-dimensional gauge field, the four-dimensional neutral Higgs boson has odd H parity while all the other standard model particles have even parity to all orders in perturbation theory. Based on H-parity conserving WWHH and ZZHH vertices, we investigate the collider signatures of Higgs dark matter production associated with a SM W or Z gauge boson at the LHC and the ILC. The final state consists of a W or a Z boson with large missing energy. We found that the level of the signal cross section is quite hopeless at the LHC while we may be able to identify it at the ILC with polarized electron beams.
