We present a search for high-mass neutral resonances using dimuon data corresponding to an integrated luminosity of 2.3 fb-1 collected in p anti-p collisions at s**(1/2) =1.96 TeV 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 sigma .

Using these cross section limits, we determine lower mass limits on sneutrinos in R-parity-violating supersymmetric models, Z' bosons, and Kaluza-Klein gravitons in the Randall-Sundrum model.

Abstract

We present a search for high-mass neutral resonances using dimuon data corresponding to an integrated luminosity of 2.3 fb-1 collected in p anti-p collisions at s**(1/2) =1.96 TeV 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 sigma . BR(p anti-p --> X --> mu mu-bar), where X is a boson with spi+n 0, 1, or 2. Using these cross section limits, we determine lower mass limits on sneutrinos in R-parity-violating supersymmetric models, Z' bosons, and Kaluza-Klein gravitons in the Randall-Sundrum model.
