Search for long-lived neutral particles decaying into lepton jets in proton-proton collisions at s = 8 TeV with the ATLAS detector
Original language description
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 LHC detectors? linear dimensions. This paper presents the results of a search for lepton jets in proton-proton collisions at the centre-of-mass energy of s=8 TeV in a sample of 20.3 fb1 collected during 2012 with the ATLAS detector at the LHC. Limits on models predicting Higgs boson decays to neutral long-lived lepton jets are derived as a function of the particle?s proper decay length.
