%0 Journal Article %T Search for displaced vertexes arising from decays of new, heavy particles in 7 TeV pp collisions in ATLAS %A F. M. Brochu %J Physics %D 2012 %I arXiv %X We present the results of a search for neutralinos decaying at a significant distance from their production point into charged hadrons and a high momentum muon, forming displaced vertexes. The analysis was performed with 33 pb^-1 of pp collision data collected by the ATLAS experiment at the LHC in 2010 at sqrt{s}= 7 TeV. The poster will show some highlights of the analysis. %U http://arxiv.org/abs/1201.1742v1
