通向暗区的拓扑门户

Topological Portal to the Dark Sector

Joe Davighi, Admir Greljo, Nudzeim Selimovic

AI总结:

提出QCD与暗区间的拓扑门户,连接三个QCD介子与两个暗π介子,作为主导门户,提供轻热非弹性暗物质场景,减弱湮灭并抑制直接探测,但为Belle II提供新对撞机信号。

摘要:

我们提出了一种独特的拓扑门户,连接量子色动力学(QCD)与一个由全局对称性破缺表征的暗区,该门户将三个QCD介子与两个暗π介子相连。当该门户被规范化为规范相互作用时,它成为两个扇区之间的主要门户,提供了一个优雅且自洽的轻热非弹性暗物质场景。固有的反对称化导致后期湮灭减弱,并抑制了直接探测信号。然而,新颖的对撞机特征为在Belle II实验中发现提供了巨大前景。

英文摘要:

We propose a unique topological portal between quantum chromodynamics (QCD) and a dark sector characterized by a global symmetry breaking, which connects three QCD to two dark pions. When gauged, it serves as the leading portal between the two sectors, providing an elegant, self-consistent scenario of light thermal inelastic dark matter. The inherent antisymmetrization leads to diminished annihilations at later times and suppressed direct detection. However, novel collider signatures offer tremendous prospects for discovery at Belle II.
