A search for prompt lepton-jets in pp collisions at √s=7TeV with the ATLAS detector
We present a search for a light (mass <2GeV) boson predicted by Hidden Valley supersymmetric models that decays into a final state consisting of collimated muons or electrons, denoted “lepton-jets”. The analysis uses 5fb −1 of s=7TeV proton–proton collision data recorded by the ATLAS detector...
