Search for Randall-Sundrum gravitons in dilepton and diphoton final states
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 D0 detector operating at the Fermilab Tevatron pp̄ Collider at s=1.96TeV. No evidence for resonant production of gravitons has been found in the data corresponding to an integrated luminosity of 260pb-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 standard model particles. © 2005 The American Physical Society.
