T宇称最简单小Higgs模型中的暗物质

Dark matter in a Simplest Little Higgs with T-parity model

Pat Kalyniak, Dmitriy Tseliakhovich

摘要:

作为标准模型的延伸,小希格斯模型可能为超对称性提供一个可行的替代方案。在小希格斯模型中引入离散的$Z_2$对称性(被称为T宇称)后,它们也包含了一个有希望的暗物质候选者。在最简单小希格斯T宇称模型中研究了作为暗物质候选者的重中微子。首先,我们计算模型的参数空间上的遗迹密度约束,然后讨论SLHT暗物质的对撞机签名。

英文摘要:

Little Higgs models may provide a viable alternative to supersymmetry as an extension of the Standard Model. After the introduction of a discrete $Z_2$ symmetry, dubbed T-parity into Little Higgs models they also contain a promising dark matter candidate. We investigate a heavy neutrino as a dark matter candidate in the Simplest Little Higgs with T-parity (SLHT) model. First we calculate relic density constraints on the parameter space of the model and then discuss collider signatures for the SLHT dark matter.
