利用CMS探测器收集的宇宙线事件的大样本来测量电磁量热计的钨酸铅（PbWO 4）中μ子的比能量损失。测量的动量范围从5 GeV/ c到1 TeV/ c。结果与整个范围内的预期一致。量热计的能量尺度，设置为120 GeV/ c的电子，验证到亚GeV区域使用能量存款，为100兆电子伏，与低动量μ子。测得PbWO 4的μ子临界能量为160 + 5 − 6 ± 8 GeV，与预期相符。这是第一次实验测定μ子临界能量。
A large sample of cosmic ray events collected by the CMS detector is exploited to measure the specific energy loss of muons in the lead tungstate (PbWO 4 ) of the electromagnetic calorimeter. The measurement spans a momentum range from 5 GeV/ c to 1 TeV/ c . The results are consistent with the expectations over the entire range. The calorimeter energy scale, set with 120 GeV/ c electrons, is validated down to the sub-GeV region using energy deposits, of order 100 MeV, associated with low-momentum muons. The muon critical energy in PbWO 4 is measured to be 160 + 5 − 6 ± 8 GeV, in agreement with expectations. This is the first experimental determination of muon critical energy.
