摘要:

用MINOS近探测器在225米水当量处记录了一个1.53 $\times$ 10 $^{9}$宇宙射线诱发的单μ子事件。地下μ介子率被观察到与有效大气温度高度相关。将μ子速率的变化与垂直有效温度的变化联系起来的系数$α_{T}$被确定为0.428 $\pm$ 0.003(stat.)$\pm$ 0.059(系统)。另一种描述是加权的有效温度,介绍了占的温度分布和μ子通量作为天顶角的函数的差异。使用后一种温度估计,确定系数为0.352 $\pm$ 0.003(统计)。$\pm$ 0.046(系统)。

英文摘要:

A sample of 1.53$\times$10$^{9}$ cosmic-ray-induced single muon events has been recorded at 225 meters-water-equivalent using the MINOS Near Detector. The underground muon rate is observed to be highly correlated with the effective atmospheric temperature. The coefficient $α_{T}$, relating the change in the muon rate to the change in the vertical effective temperature, is determined to be 0.428$\pm$0.003(stat.)$\pm$0.059(syst.). An alternative description is provided by the weighted effective temperature, introduced to account for the differences in the temperature profile and muon flux as a function of zenith angle. Using the latter estimation of temperature, the coefficient is determined to be 0.352$\pm$0.003(stat.)$\pm$0.046(syst.).
