Search for Randall-Sundrum gravitons with 1 fb-1 of data from ppbar collisions at sqrt(s)=1.96 TeV

Abstract

Using 1 fb-1 of data from ppbar collisions at sqrt(s)=1.96 TeV at the Fermilab Tevatron collider collected by the D0 detector, we search for decays of Kaluza-Klein excitations of the graviton in the Randall-Sundrum model of extra dimensions to e+e- and diphotons. We set 95% confidence level upper limits on the production cross section times branching fraction which translate into lower limits on the mass of the lightest excitation between 300 and 900 GeV for values of the coupling k/M(Planck) between 0.01 and 0.1.
