The data were collected with the D0 detector at the Fermilab Tevatron Collider and correspond to 6.3  fb(−1) of integrated luminosity. The observed missing transverse energy distribution is well described by the standard model prediction, and 95% C.L. limits are derived on two realizations of theories beyond the standard model. In a gauge-mediated supersymmetry breaking scenario, the breaking scale Λ is excluded for Λ<124  TeV. In a universal extra dimension model including gravitational decays, the compactification radius R(c) is excluded for R−1(c)<477  GeV.Article10.1103/PhysRevLett.105.221802openAccess
