Search for New Dimuon Resonances and
Randall-Sundrum Gravitons (decaying to ee, μμ, γγ)
at the Collider Detector at Fermilab

A search for new dimuon mass resonances using 5.7 fb^-1 of data recorded by the CDF II detector is presented. No significant excess over the expected standard model prediction is observed. The results are intepreted in the Randall-Sundrum (RS) model. Combined with the 5.4 fb^-1 diphoton analysis, and the 5.7 fb^-1 dielectron analysis (ee+γγ analysis), the RS-graviton mass limit for the coupling k/M_Pl=0.1 is 1111 GeV/c² making it the strongest limit to date.
