Search for Randall-Sundrum Gravitons in the Dielectron and Diphoton Final States with 5.4 fb(-1) of Data from p(p)over-bar Collisions at root s=1.96 TeV

Abstract

Using 5.4 fb(-1) of integrated luminosity from p (p) over bar collisions at root s = 1.96 TeV collected by the D0 detector at the Fermilab Tevatron Collider, we search for decays of the lightest Kaluza-Klein mode of the graviton in the Randall-Sundrum model to ee and gamma gamma. We set 95% C.

L. lower limits on the mass of the lightest graviton between 560 and 1050 GeV for values of the coupling k/(M) over bar (P1) between 0.01 and 0.1.
