Muon Trigger Algorithm for the HL-LHC Upgrade of the CMS Experiment
MetadataShow full item record
After the successful discovery of the Higgs Boson at the Large Hadron Collider (LHC), efforts have shifted toward the understanding of the dynamic behind the Higgs mechanism and the implied consequences that can further extend the Standard Model of Particle Physics. One class of models of new physics implies existence of ”hidden” sectors of particles, some of which could be produced at the upgraded LHC. In many scenarios, such particles may have an appreciable lifetime and can decay to pairs of muons leading to signatures with muon pairs produced away from the beamline. However, existing muon trigger algorithms show large inefficiencies for detecting such muons. Therefore, we propose and investigate a conceptually new trigger algorithm for reconstructing and measuring momenta of displaced muons using information from muon spectrometers only, which can be implemented as part of the re-design of the CMS Level-1 muon trigger for the HL-LHC to maintain CMS sensitivity to signatures with displaced muons.
