Performance of the CMS muon trigger system in proton-proton collisions at √(s) = 13

A. M. Sirunyan, A. Tumasyan, W. Adam, T. Bergauer et autres

Abstract The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015–2018) the LHC achieved instantaneous luminosities as high as 2 × 1034 while delivering proton-proton collisions …
