# Search for diphoton events with large missing transverse energy in 6.3 fb$^{-1}$ of $\mathbf{p\bar{p}}$ collisions at $\mathbf{\sqrt{s}=1.96}$~TeV

### Description

We report a search for diphoton events with large missing transverse energy produced in p{bar p} collisions at {radical}s = 1.96 TeV. The data were collected with the D0 detector at the Fermilab Tevatron Collider, and correspond to 6.3 fb{sup -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 {Lambda} is excluded for {Lambda} &lt; 124 TeV. In a universal extra dimension model including gravitational decays, ... continued below

In a gauge mediated supersymmetry breaking scenario, the breaking scale {Lambda} is excluded for {Lambda} &lt; 124 TeV. In a universal extra dimension model including gravitational decays, the compactification radius R{sub c} is excluded for R{sub c}{sup -1} &lt; 477 GeV.
