论文摘要
尽管大部分是僻静的，但黑暗区域的颗粒可能会通过小质量尺寸4 milharge，质量差5磁和电偶极矩或质量差异6 Anapole矩和电荷半径与光子进行微弱相互作用。如果充分光线，LHC可能会在遥远的方向上产生这些颗粒的强烈而直接的光束。我们研究了在正向物理设施（FPF）的正向液体氩实验（FLARE）检测器中，通过其电子散射特征来搜索具有电磁形式因素的前景。我们发现，耀斑可以在100 MeV到100 GEV区域中提供偶极矩和强敏感性的亚GEV黑暗颗粒的新探针。这可以使用闪烁特征或暗物质直接检测来补充其他搜索策略，并允许探测边缘异常动机的强烈相互作用。与Formosa检测器一起，这导致了在FPF中寻找Millicharged颗粒的非常多样化和领先的实验程序。
Despite being mostly secluded, dark sector particles may feebly interact with photons via a small mass-dimension 4 millicharge, a mass-dimension 5 magnetic and electric dipole moment, or a mass-dimension 6 anapole moment and charge radius. If sufficiently light, the LHC may produce an intense and collimated beam of these particles in the far forward direction. We study the prospects of searching for such dark sector particles with electromagnetic form factors via their electron scattering signature in the Forward Liquid Argon Experiment (FLArE) detector at the Forward Physics Facility (FPF). We find that FLArE can provide new probes of sub-GeV dark particles with dipole moments and strong sensitivities for millicharged particles in the 100 MeV to 100 GeV region. This complements other search strategies using scintillation signatures or dark matter direct detection and allows for probing strongly interacting dark matter motivated by the EDGES anomaly. Along with the FORMOSA detector, this leads to a very diverse and leading experimental program in the search for millicharged particles in the FPF.
