| Abstract | 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 $160^{+5}_{-6} \pm 8$ GeV, in agreement with expectations. |
