Trigger efficiency for the $\tilde{\tau}$ signals as a function of $\beta$ for $\text{abs(}\eta\text{)}<0.3$. The up and down variations are conservatively estimated assuming a delay of 1.5 ns in the muon chambers (equivalent to the time resolution of the chambers) and are used to evaluate the signal systematic uncertainties.

针对赝快度（pseudorapidity, η）的绝对值小于0.3的情况，$ ilde{ au}$信号的触发效率随参数β的变化关系。该数据集的上下涨落通过保守估算得到，假设缪子探测器（muon chambers）存在1.5纳秒的延迟，该延迟等价于探测器的时间分辨率，上述涨落被用于评估信号的系统不确定度。
