论文摘要
暗物质是黑暗部门的一部分吗？ The possibility of a dark sector neutral under Standard Model (SM) forces furnishes an attractive explanation for the existence of Dark Matter (DM), and is a compelling new-physics direction to explore in its own right, with potential relevance to fundamental questions as varied as neutrino masses, the hierarchy problem, and the Universe's matter-antimatter asymmetry.由于黑暗扇区通常与普通物质相结合，并且由于它们自然可以具有MEV至GEV质量并尊重SM的对称性，因此它们仅受高能量撞机数据和精度原子测量的轻度约束。然而，即将到来的和提议的强度范围实验将为黑暗部门的物理学提供前所未有的窗口，这是2018年《暗物质新计划》（DMNI）BRN报告的优先研究方向。对该计划的支持 - 以多功能实验进行黑暗行业分析的形式，实现获得DMNI资金的强度 - 范围实验的实现，DMNI支持的扩展，DMNI支持以探索DM的全部广度，并探索可见的最终态度签名（尤其是长期的范围），以实现良好的良好范围，并在良好的范围内训练，并旨在促进黑暗的努力，并征服了黑暗的努力 - DM里程碑，并大大提高了强度 - 范围实验的潜力，发现发现了腐烂回到SM颗粒的黑区域颗粒。
Is Dark Matter part of a Dark Sector? The possibility of a dark sector neutral under Standard Model (SM) forces furnishes an attractive explanation for the existence of Dark Matter (DM), and is a compelling new-physics direction to explore in its own right, with potential relevance to fundamental questions as varied as neutrino masses, the hierarchy problem, and the Universe's matter-antimatter asymmetry. Because dark sectors are generically weakly coupled to ordinary matter, and because they can naturally have MeV-to-GeV masses and respect the symmetries of the SM, they are only mildly constrained by high-energy collider data and precision atomic measurements. Yet upcoming and proposed intensity-frontier experiments will offer an unprecedented window into the physics of dark sectors, highlighted as a Priority Research Direction in the 2018 Dark Matter New Initiatives (DMNI) BRN report. Support for this program -- in the form of dark-sector analyses at multi-purpose experiments, realization of the intensity-frontier experiments receiving DMNI funds, an expansion of DMNI support to explore the full breadth of DM and visible final-state signatures (especially long-lived particles) called for in the BRN report, and support for a robust dark-sector theory effort -- will enable comprehensive exploration of low-mass thermal DM milestones, and greatly enhance the potential of intensity-frontier experiments to discover dark-sector particles decaying back to SM particles.
