Long-lived particles decaying into pair of muons, illustration
Illustration of two types of long-lived particles decaying into a pair of muons, showing how the signals of the muons can be traced back to the long-lived particle decay point using data from the tracker and muon detectors. The CMS (Compact Muon Solenoid) experiment at the Large Hadron Collider in CERN (European Laboratory for Particle Physics) is conducting a study on the production of 'dark photons' in the decay of Higgs bosons in the detector. Dark photons are long-lived and 'exotic' particles that are not a part of the Standard Model of particle physics. The study looks into at the possibility of detecting these particles by observing their decay into 'displaced muons'., by CMS/CERN/SCIENCE PHOTO LIBRARY
