The Nuclear Physics Group, as part of the CMS collaboration, just submitted a paper (https://doi.org/10.48550/arXiv.2404.17377) studying the muon performance of the CMS Experiment from proton-proton to the tough conditions found in a heavy ion collision. The study was led by graduate students Ota Kukral and Jared Jay. It used events where particles, such as the Z boson, decayed into a muon-antimuon pair to see how well the muons could be measured from among the thousands of other particle tracks emerging from a high-energy heavy ion collision.

A news briefing prepared by Dr. Heather Folsom, a visiting scholar working with the Nuclear Physics Group, and Prof. Manuel Calderon de la Barca, can be found in the News pages of the CMS Experiment (https://cms.cern/news/using-muons-check-cms-detector-toughest-conditions).
