压缩Inert Doublet模型

Compressing the Inert Doublet Model

Nikita Blinov, Jonathan Kozaczuk, David E. Morrissey, Alejandro de la Puente

摘要:

惰性双重模型依赖于离散对称性来防止新标量与标准模型费米子的耦合。这稳定了最轻的惰性状态,然后可以有助于观察到的暗物质密度。在存在额外的近似对称时,奇异标量的谱可以被压缩。在这里,我们研究这种情况的现象学和宇宙学的影响。我们从LEP中推导出压缩惰性双态模型的新极限,并概述了在暗物质实验、大型强子对撞机和未来对撞机中排除和发现该模型的前景。

英文摘要:

The Inert Doublet Model relies on a discrete symmetry to prevent couplings of the new scalars to Standard Model fermions. This stabilizes the lightest inert state, which can then contribute to the observed dark matter density. In the presence of additional approximate symmetries, the resulting spectrum of exotic scalars can be compressed. Here, we study the phenomenological and cosmological implications of this scenario. We derive new limits on the compressed Inert Doublet Model from LEP, and outline the prospects for exclusion and discovery of this model at dark matter experiments, the LHC, and future colliders.
