Abstract

We search for high-mass resonances decaying into Z boson pairs using data corresponding to 6 fb(-1) collected by the CDF experiment in p (p) over bar collisions at root s = 1.96 TeV. The search is performed in three distinct final states: ZZ -> l(+)l(-)l(+)l(-), ZZ -> l(+)l(-) nu nu, and ZZ -> l(+)l(-)jj. For a Randall-Sundrum graviton G*, the 95% CL upper limits on the production cross section times branching ratio to ZZ, sigma(p (p) over bar -> G* -> ZZ), vary between 0.26 pb and 0.045 pb in the mass range 300 < M(G*) < 1000 GeV/c(2).
