论文摘要
具有紧密耦合的黑暗扇区的标准模型扩展可以诱导软夸克的高质量状态。这样的最终状态会触发极有效的反核形成。我们表明，暗物质歼灭或腐烂到一个强耦合扇区可以极大地增强宇宙射线的抗核里通量 - 在$ {^4 \ overline {\ text {he text {he}}}}} $的情况下，六个数量级。在这项工作中，我们认为暂定$ {^3 \ edline {\ text {he}}} $和$ {^4 \ overline {\ text {he}} $事件由AMS-02协作报告的事件可能是在本质上认识的第一个迹象。
Standard Model extensions with a strongly coupled dark sector can induce high-multiplicity states of soft quarks. Such final states trigger extremely efficient antinucleus formation. We show that dark matter annihilation or decay into a strongly coupled sector can dramatically enhance the cosmic-ray antinuclei flux -- by six orders of magnitude in the case of ${^4\overline{\text{He}}}$. In this work, we argue that the tentative ${^3\overline{\text{He}}}$ and ${^4\overline{\text{He}}}$ events reported by the AMS-02 collaboration could be the first sign of a strongly coupled dark sector observed in nature.
