A search for SUSY with Razor kinematic variables in proton-proton collisions at $\sqrt{s}$=8 TeV with the ATLAS detector at the LHC

The experimental signature for our search is jets and missing energy. The Razor variables are built using two mega-jets and are designed to discriminate against QCD multi-jets background. Contributions from dominant background sources (Z+jets, W+jets, $t\bar{t}$, and QCD) are estimated using control regions in data. The result is interpreted in the context of the simplified models of squark-pair production.
