Physical Review D 78,1 ( 2008 )
We report the results of a search for the anomalous production of a massive particle decaying to four electrons via two Z(0) bosons in 1.1 fb(-1) of p (p) over bar collisions at root s = 1.96 TeV collected by the CDF II detector at Fermilab. We employ optimized electron identification criteria to maximize acceptance and efficiency. We estimate the backgrounds in the invariant mass range 500-1000 GeV/c(2) to be 0.028 +/- 0.009(stat) +/- 0.011(syst) events. We observe zero events in this search region. Assuming a Randall-Sundrum graviton production model, we set 95% C.L. limits on sigma x BF(G -> Z(0)Z(0)) < 4-6 pb, depending on the graviton mass.
