Search for Supersymmetry with displaced vertices and muons using the ATLAS detector Chavez Gonzalez, Ricardo


The results of a search for Supersymmetry (SUSY) using the full 2012 ATLAS dataset with an integrated luminosity of 20.3 fb-¹ at √s = 8 TeV are interpreted and presented in the context of gauge mediated SUSY. No events with at least one long-lived particle that decays at a significant distance from its production point into two muons were observed in data. No vertices passed the selection criteria which is consistent with the Standard Model background of 10-³ vertices. The strongest exclusion is observed between 20 mm and 40 mm, with an upper limit of around 10 fb on the gluino pair production cross-section.
