    Search for Long-Lived Neutral Particles Decaying into Lepton Jets in Proton-Proton Collisions at √s = 8 TeV with the ATLAS Detector 

    Aad, G.; Abbott, B.; Abdallah, J.; Abdel Khalek, S.; Abdinov, O.; Aben, R.; Abi, B.; Izen, Joseph M.; Leyton, Michael; Lou, Xinchou; Namasivayam, Harisankar; Reeves, Kendall; ATLAS Collaboration (Springer, 2014-11-18)
    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 ...
