Abstract
We present a search for high-mass neutral resonances using dimuon data corresponding to an integrated luminosity of collected in collisions at by the CDF II detector at the Fermilab Tevatron. No significant excess above the standard model expectation is observed in the dimuon invariant-mass spectrum. We set 95% confidence level upper limits on , where is a boson with spin-0, 1, or 2. Using these cross section limits, we determine lower mass limits on sneutrinos in -parity-violating supersymmetric models, bosons, and Kaluza-Klein gravitons in the Randall-Sundrum model.
