论文摘要
与超高能量宇宙射线（UHECR）数据相比，我们研究了空气淋浴模拟中观察到的次数不足。基于爱丽丝合作报告中观察到的高能强化碰撞中陌生产量的增强，伴随的$π\ leftrightArrow k $交换被认为是通过其对淋浴开发的相应影响来解决MUON异常的基石。我们根据$π\ leftrightarrow k $交换概率$ f_s $构建玩具模型。我们在可以容纳UHECR数据的伪the词方面提出了$ f_s $的参数化。展望未来，我们使用LHC中微子探测器收集的大量数据（例如Faser $ν$）以及向前物理设施的实验来探讨模型改进的潜在策略。我们计算对$ f_s $的相应灵敏度，并表明这些实验将能够探测模型相位空间。
We investigate the observed muon deficit in air shower simulations when compared to ultrahigh-energy cosmic ray (UHECR) data. Based upon the observed enhancement of strangeness production in high-energy hadronic collisions reported by the ALICE Collaboration, the concomitant $π\leftrightarrow K$ swap is considered as the keystone to resolve the muon anomaly through its corresponding impact on the shower development. We construct a toy model in terms of the $π\leftrightarrow K$ swapping probability $F_s$. We present a parametrization of $F_s$ in terms of the pseudorapidity that can accommodate the UHECR data. Looking to the future, we explore potential strategies for model improvement using the massive amounts of data to be collected by LHC neutrino detectors, such as FASER$ν$ and experiments at the Forward Physics Facility. We calculate the corresponding sensitivity to $F_s$ and show that these experiments will be able to probe the model phase space.
