Title: Search for randall-sundrum gravitons in dilepton and diphoton final states

Abstract

We report the first direct search for the Kaluza-Klein (KK) modes of Randall-Sundrum gravitons using dielectron, dimuon, and diphoton events observed with the DØ detector operating at the Fermilab Tevatron pp¯ Collider at √ s = 1.96 TeV. No evidence for resonant production of gravitons has been found in the data corresponding to an integrated luminosity of ≈ 260 pb -1. Lower limits on the mass of the first KK mode at the 95% C.L. have been set between 250 and 785 GeV, depending on its coupling to SM particles.
