全息暗物质与希格斯玻色子

Holographic Dark Matter and Higgs

J. Lorenzo Diaz-Cruz

摘要:

我们确定了可能的暗物质候选人内的强相互作用模型,其中电弱对称性破缺是由一个轻复合希格斯玻色子玻色子。在这些模型中,希格斯玻色子以全息假金石玻色子的形式出现,而暗物质可以被识别为费米子复合态X^0,它通过守恒("暗“)量子数而变得稳定。提出了一种有效的Higgs和暗物质的拉格朗日描述,其中包含了被尺度Λ i抑制的高维算符。这些算符将导致偏离标准希格斯粒子的性质,这些性质可以在未来的对撞机(LHC,ILC)上测量,从而提供关于暗物质尺度的信息。预计暗物质X^0的质量为O(TeV),这与从宇宙学边界和对暗物质的实验搜索中提取的值一致。

英文摘要:

We identify possible dark matter candidates within the class of strongly interacting models where electroweak symmetry breaking is triggered by a light composite Higgs boson. In these models, the Higgs boson emerges as a Holographic pseudo-goldstone boson, while dark matter can be identified as a fermionic composite state X^0, which is made stable through a conserved (``dark'') quantum number. An effective lagrangian description of both the Higgs and dark matter is proposed, that includes higher-dimensional operators suppressed by an scale Λ_i. These operators will induce deviations from the standard Higgs properties that could be meassured at future colliders (LHC,ILC), and thus provide information on the dark matter scale. The dark matter X^0, is expected to have a mass of order O(TeV), which is in agreement with the values extracted from the cosmological bounds and the experimental searches for dark matter.
