Recent Results from GMSB SUSY Searches at D0
Tim Christiansen
Abstract
Using approximately 41 pb-1 of proton-antiproton collisions, recorded with the D0 detector during the TeVatron Run II, this document describes the search for minimal GMSB SUSY signal (with a neutralino as next-to-lightest supersymmetric particle) in di-photon + missing ET events. Since no deviation from the Standard Model is observed, a 95% confidence level upper limit on the signal cross-section is calculated. This is translated into a lower limit on the neutralino mass, yielding m(chi10) > 66 GeV in the context of the Snowmass GMSB model line.
