对撞机上的模糊希格斯玻色子

Obscure Higgs boson at Colliders

Priyotosh Bandyopadhyay, Antonio Costantini

摘要:

在这项研究中,我们考虑一个复杂的超荷零三重标量的标准模型的扩展。在这种情况下,其中一个带电的希格斯玻色子玻色子保持纯粹的三重态,不与费米子耦合,使其在对撞机上难以实现。此外,物理赝标是一个纯的三重态,这种纯度使它成为一个合适的暗物质候选者,而不需要离散对称性,不像其他的扩展。根据遗迹密度和直接暗物质搜索实验的结果,其质量为$\sim 1.35-1.60$ TeV。在LHC和MATHUSLA上研究了纯三重态带电希格斯粒子产生位移信号及其灵敏度。通过计算这些奇异标量的产生截面和主要衰变模式,指出了它们在强子/μ子对撞机上的应用前景。我们还提出了预期达到的三重态在多TeV μ子对撞机。

英文摘要:

In this study we consider an extension of the Standard Model with a complex hypercharge zero triplet scalar. In this scenario one of the charged Higgs bosons remains purely triplet and does not couple to the fermions, making it elusive at colliders. Also the physical pseudoscalar is a pure triplet and this purity makes it a suitable dark matter candidate without the need of discrete symmetries, unlike other extensions. The bounds from relic density and direct dark matter search experiments select its mass to be $\sim 1.35-1.60$ TeV. The pure triplet charged Higgs gives rise to displaced signatures and their sensitivity at LHC and MATHUSLA have been studied. The prospects at present and future hadron/muon colliders of such exotic scalars are pointed out by calculating their productions cross-section and dominant decay modes. We present also the expected reach for the triplet states at a multi-TeV muon collider.
