Systematical Uncertainties for SUSY searches in CMS — •Altan Cakir, Wim de Boer, Markus Bonsch, Tim Hanisch, Martin Niegel, Fedor Ratnikov, Christian Skole, Daniel Troendle, Valery Zhukov, and Eva Ziebarth — IEKP, Karlsruhe Institute Of technology

Alpgen, Madgraph, MC@NLO and Sherpa MC generators for LHC have been compared in distributions used for SUSY searches. Before the MC simulations are tuned to the real data, these differences can be considered as theoretical systematic uncertainties which can reach 30% for tails of jet transverse energy, missing transverse energy and jet multiplicities.
