These particles can also be long-lived with decay length comparable to, or even larger than, the LHC detectors{\textquoteright} linear dimensions. This paper presents the results of a search for lepton jets in proton-proton collisions at the centre-of-mass energy of root s = 8 TeV 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{\textquoteright}s proper decay length.", optnote="WOS:000345639900001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2037), last updated on Fri, 09 Jan 2015 00:51:18 +0000", issn="1029-8479", doi="10.1007/JHEP11(2014)088", opturl="http://arxiv.org/abs/1409.0746", opturl="https://doi.org/10.1007/JHEP11(2014)088", archivePrefix="arXiv", eprint="1409.0746", language="English" }
