The study of cosmic rays with underground accelerator experiments started with the LEP detectors at CERN. ALEPH, DELPHI and L3 studied some properties of atmospheric muons such as their multiplicity and momentum. In recent years, an extension and improvement of such studies has been carried out by ALICE and CMS experiments. Along with the LHC high luminosity program some experimental setups have been proposed to increase the potential discovery of LHC. An example is the MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles detector (MATHUSLA) designed for searching of Ultra Stable Neutral Particles, predicted by extensions of the Standard Model such as supersymmetric models, which is planned to be a surface detector placed 100 meters above ATLAS or CMS experiments. Hence, MATHUSLA can be suitable as a cosmic ray detector. In this manuscript the main results regarding cosmic ray studies with LHC experimental underground apparatus are summarized. The potential of future MATHUSLA proposal is also discussed.

在 LHC 使用实验装置进行宇宙射线研究

通过地下加速器实验对宇宙射线的研究始于 CERN 的 LEP 探测器。ALEPH、DELPHI 和 L3 研究了大气 μ 子的一些特性，例如它们的多样性和动量。近年来，ALICE和CMS实验对此类研究进行了扩展和改进。随着 LHC 高亮度计划，一些实验装置已被提议以增加 LHC 的潜在发现。一个例子是超稳定中性粒子探测器 (MATHUSLA) 的 MAssive Timing Hodoscope，其设计用于搜索超稳定中性粒子，由标准模型的扩展（如超对称模型）预测，该模型计划是放置在 100 米上方的表面探测器ATLAS 或 CMS 实验。因此，MATHUSLA 可以适合作为宇宙射线探测器。在这份手稿中，总结了使用 LHC 实验地下设备进行宇宙射线研究的主要结果。还讨论了未来 MATHUSLA 提案的潜力。
