SU(6)/ SO(6)复合Higgs模型中的单态暗物质

A Singlet Dark Matter in the SU(6)/SO(6) Composite Higgs Model

Haiying Cai, Giacomo Cacciapaglia

摘要:

单重标量暗物质可以自然地出现在复合希格斯模型中,作为一个额外的稳定的伪南布-戈德斯通玻色子。我们在一个基于$SU(6)/SO(6)$的模型中研究了这样一个候选者的性质,其中轻夸克质量由4-费米子相互作用产生。耦合中的非线性的存在允许使质量为$400 < m_{\rm DM} < 1000$ GeV的残余密度饱和,并且在来自直接检测和间接检测的结合中存活。可行的参数区域在未来升级的敏感性范围内,如XENONNT和LZ。

英文摘要:

Singlet scalar Dark Matter can naturally arise in composite Higgs models as an additional stable pseudo-Nambu-Goldstone boson. We study the properties of such a candidate in a model based on $SU(6)/SO(6)$, with the light quark masses generated by 4-fermion interactions. The presence of non-linearities in the couplings allows to saturate the relic density for masses $400 < m_{\rm DM} < 1000$ GeV, and survive the bound from Direct Detection and Indirect Detection. The viable parameter regions are in reach of the sensitivities of future upgrades, like XENONnT and LZ.
