我们研究具有GeV尺度禁闭的暗非阿贝尔规范扇区。假设暗扇区仅与标准模型微弱耦合，而其低能谱可能包含长寿命味对角暗介子。这些态的信号特别适合电子离子对撞机，在那里无需硬触发要求且能够记录软末态粒子，可对暗强子化动力学进行补充探测。我们给出一个基准门户构造，讨论类轴矢媒介子与暗介子之间的混合，并确定由此产生的位移衰变特征。
英文摘要
We study a dark non-Abelian gauge sector with GeV-scale confinement. The dark sector is assumed to couple only feebly to the Standard Model, while its low-energy spectrum may contain long-lived flavor-diagonal dark pions. Signals of these states are particularly well suited to the Electron-Ion Collider (EIC), where the absence of a hard trigger requirement and the capability to record soft final-state particles offer a complementary probe of dark hadronization dynamics. We present a benchmark portal construction, discuss the mixing between an axion-like mediator and dark pions, and identify the resulting displaced-decay signature.
