Search for disappearing tracks as a signature of new long-lived particles in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2377 more
- 19 Apr 2018 - 
TL;DR: In this paper, a search for long-lived charged particles that decay within the LHC detector and produce the signature of a disappearing track is presented, which is an isolated track with missing hits in the outer layers of the silicon tracker, little or no energy in associated calorimeter deposits, and no associated hits in muon detectors.
