We present a search for a new narrow, spin-1, high mass resonance decaying to {mu}{sup +}{mu}{sup -}+X, using a matrix-element-based likelihood and a simultaneous measurement of the resonance mass and production rate. In data with 4.6 fb{sup -1} of integrated luminosity collected by the CDF detector in pp collisions at {radical}(s)=1960 GeV, the most likely signal cross section is consistent with zero at 16% confidence level. We therefore do not observe evidence for a high mass resonance and place limits on models predicting spin-1 resonances, including M>1071 GeV/c{sup 2} at 95% confidence level for a Z{sup '} boson with the same couplings to fermions as the Z boson.
