Abstract	A search is performed for heavy particle pairs produced in $\sqrt{s}$ = 7~TeV proton-proton collisions with $\sim$ 800~pb$^{-1}$ of data collected by the CMS experiment in 2011 at the CERN Large Hadron Collider. The search is sensitive to generic supersymmetry models provided superpartner particles are kinematically accessible, with minimal assumptions on properties of the lightest superpartner particle. The kinematic consistency of the selected events is tested against the hypothesis of heavy particle pair production using the dimensionless {\it razor} variable $R$, related to the missing transverse energy $E_T^{miss}$. The new physics signal is characterized by a broad peak in the distribution of $M_R$, an event-by-event indicator of the heavy particle mass scale. After background modeling based on data no significant deviation is observed from the Standard Model expectation. The results are interpreted in the context of the Constrained Minimal Supersymmetric Standard Model.
