Resumen/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 pp̅ collisions at √s=1.96  TeV. The search is performed in three distinct final states: ZZ→ℓ+ℓ-ℓ+ℓ-, ZZ→ℓ+ℓ-νν, 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, σ(pp̅ →G*→ZZ), vary between 0.26 pb and 0.045 pb in the mass range 300<MG*<1000  GeV/c2.
