Abstract	An update of the search for supersymmetry in events with jets and missing transverse energy, based on the analysis in Ref.~\cite{RA1Paper}, is presented. The results are based on a data sample of 1.1 fb$^{-1}$ of integrated luminosity recorded at $\sqrt{s}$ = 7 TeV. In this search, the variable $\alpha_{\rm T}$ is used as the main discriminator between events with real and fake missing transverse energy, and no excess of events over the Standard Model expectation is found. Given this agreement, exclusion limits in the parameter space of the constrained minimal supersymmetric model are set. In this model, squark and gluino masses of 1.1 TeV are excluded for values of the common scalar mass at the GUT scale $m_0 < 0.5$ TeV.
