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...

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. © 2013 CERN 2013 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_03702693_v719_n4-5_p299_Aad http://hdl.handle.net/20.500.12110/paper_03702693_v719_n4-5_p299_Aad
