论文摘要
尽管QCD轴轴通常被认为必然很轻（$ \ lyssim $ ev），但最近的工作为重轴开辟了一个可行而有趣的参数空间，该空间解决了强大的CP和轴突质量问题。这些动机良好的重轴以及通用的轴突状粒子，要求在对撞机和梁转储环境的GEV群众中进行探索。主要即将到来的中微子实验，深地下中微子实验（Dune），也是一个强大的梁转储实验，它通过其多功能近探测器（ND）复合物启用。在这项研究中，我们通过详细的分析表明，沙丘ND对质量对$ 20 $ MEV至$ 2 $ GEV的沉重轴承具有独特的敏感性，这与其他未来实验的补充。
While the QCD axion is often considered to be necessarily light ($\lesssim$ eV), recent work has opened a viable and interesting parameter space for heavy axions, which solve both the Strong CP and the axion Quality Problems. These well-motivated heavy axions, as well as the generic axion-like-particles, call for explorations in the GeV mass realm at collider and beam dump environments. The primary upcoming neutrino experiment, Deep Underground Neutrino Experiment (DUNE), is simultaneously also a powerful beam dump experiment, enabled by its multipurpose Near Detector (ND) complex. In this study, we show with detailed analyses that the DUNE ND has a unique sensitivity to heavy axions for masses between $20$ MeV and $2$ GeV, complementary to other future experiments.
