Search for disappearing tracks in proton-proton collisions at $\sqrt{s} = 13$ TeV /CMS Collaboration
A search is presented for long-lived charged particles that decay within the silicon tracker of the CMS detector. Such particles can produce a "disappearing track" signature, identified as an isolated track with no associated hits in the muon detectors, little calorimeter energy deposits, and missing hits in the outermost layers of the silicon tracker.
