Keywords: | Hadron-Hadron Scattering | Issue Date: | 2014 | Publisher: | Springer Nature | Serial title, monograph or event: | Journal of High Energy Physics | Volume: | 2014 | Issue: | 11 | 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 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= 8TeV in a sample of 20.3 fb−1 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. | URI: | https://hdl.handle.net/10316/109474 | DOI: | 10.1007/JHEP11(2014)088 | Rights: | openAccess |
