论文摘要

强烈相互作用的巨大颗粒是可行的暗物质候选者。我们考虑了一个黑暗的$ sp(4)$仪表理论,其中$ n_f = 2 $ fermions在伪真实的基本表示中,并构建手性低能量有效理论。我们确定了风味多重结构和手性Lagrangian,包括用于质量分级和非分类口味的Wess-Zumino-witten术语。然后,我们研究了$ U(1)'$量规对称的可能的指控分配,强调黑暗状态的稳定性,并为戈德斯通玻色子和矢量谐振提供了完整的拉格朗日描述,包括Wess-Zumino witter术语。最后,我们使用专用的晶格模拟来确定手性低能量有效理论的有效性和低能常数。这项工作代表了对这一非亚洲理论的自洽研究。因此,它为与暗物质问题有关的未来现象学探索提供了一个框架。

Strongly interacting massive particles are viable dark matter candidates. We consider a dark $Sp(4)$ gauge theory with $N_f=2$ fermions in the pseudo-real fundamental representation and construct the chiral low-energy effective theory. We determine the flavor multiplet structure and the chiral Lagrangian, including the Wess-Zumino-Witten term for mass-degenerate and non-degenerate flavors. We then study the possible charge assignments under a $U(1)'$ gauge symmetry, emphasizing on dark state stability, and provide the full Lagrangian description for Goldstone bosons and vector resonances, including the Wess-Zumino-Witten term. Finally, we use dedicated lattice simulations to determine the chiral low-energy effective theory's validity and low-energy constants. This work represents a self-consistent study of this non-Abelian theory. It thereby provides a framework for future phenomenological exploration in connection to the dark matter problem.
