Prospectives for stop searches at ATLAS and CMS

The search for supersymmetric partners of the top quark, stop squark, could result in the early discovery of physics beyond the Standard Model at the LHC. We present here the searches for stop squark within the mSUGRA model at ATLAS and CMS detectors. Results of simulation studies are presented. Search for the light stop squark in the low mass SUSY model, originating from the gluino decay, using the final state tb invariant mass at ATLAS is described. Inclusive stop search in the intermediate scenario, using the events with top candidate, leptons and missing energy at CMS is also presented. The discovery prospects in both studies are focused at early data.
