Florida State University College of Arts and Sciences Search for Large Extra Dimensions via Single Photon plus Missing Energy Final States
- EDGAR F. CARRERA, Edgar F. Carrera, +4 authors Alexey Ferapontov
We report the results of a search for GMSB SUSY in the diphoton final state using 760 pb of data collected by the DØ Experiment at the Fermilab Tevatron Collider in 2002-2005. No excess of events above the standard model background has been found, and a lower limit on the lightest neutralino (chargino) mass of 120 (220) GeV has been set at the 95% C.L. These are the most stringent limits in the class of models considered in this analysis to date.
