A search for prompt lepton-jets in pp collisions at √s = 8 TeV with the ATLAS detector

Abstract: A search is presented for a new, light boson with a mass of about 1 GeV and decaying promptly to jets of collimated electrons and/or muons (lepton-jets). The analysis is performed with 20.3 fb −1 of data collected by the ATLAS detector at the Large Hadron Collider in proton-proton collisio...
