Abstract:

We present a search for a light (mass 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 at the Large Hadron Collider to search for the following signatures: single lepton-jets with at least four muons pairs of lepton-jets, each with two or more muons and pairs of lepton-jets with two or more electrons. This study finds no statistically significant deviation from the Standard Model prediction and places 95% confidence-level exclusion limits on the production cross section times branching ratio of light bosons for several parameter sets of a Hidden Valley model.
