Search for long-lived neutral particles decaying into lepton jets in proton-proton collisions at √s= 8TeV with the ATLAS detector

Abstract: Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called “lepton jets”). These particles can also be long-lived with decay length comparable to, or even larger than, the...
