Search for dark-photons decaying to lepton-jets with the ATLAS detector at LHC

Several new physics models predict the existence of neutral particles with macroscopic life-times that decay to pairs of leptons and light hadrons with a jet-like structure (lepton-jets). These particles, decaying outside of the interaction region, will give rise to striking signatures in the detect...

description Several new physics models predict the existence of neutral particles with macroscopic life-times that decay to pairs of leptons and light hadrons with a jet-like structure (lepton-jets). These particles, decaying outside of the interaction region, will give rise to striking signatures in the detectors at the LHC. These can be detected through numerous unconventional signatures: long time-of-flight, late calorimetric energy deposits or displaced vertices. The most recent ATLAS results based on 36\ifb of data collected in proton-proton collisions at \sqrt(s)=13TeV recorded in 2015-2016 are presented. Prospects for the search for these particles with the ATLAS detector upgrade at HL-LHC are also given.
