With the start of LHC data taking the detector performance and the realistic estimation of the Standard Model (SM) background are important to search for new physics discovery channels.Our interest is focused on the scenario, suggested by the interpretation of the EGRET excess of diffuse Galactic gamma rays as a signal of dark matter annihilation. The prime signatures distinguishing gluino productions from the SM background are jet multiplicity and missing transverse energy. In this talk the background studies based on the differences of vector boson production with Alpgen,Sherpa and Pythia generators, are compared in view of possible effects for the SUSY searches.
