Search for Diphoton Events with Large Missing Transverse Energy in 6.3 fb-1 of p$$\bar{p}$$ Collisions using the D0 Detector at the Fermilab Tevatron Collider
- Columbia Univ., New York, NY (United States)
A search for diphoton events with large missing transverse energy produced in p$$\bar{p}$$ collisions at √s = 1.96 TeV is presented. The data were collected with the D0 detector at the Fermilab Tevatron Collider between 2002 and 2010, 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 Rc is excluded for Rc-1 < 477 GeV.
