We present a search for a new narrow, spi+n-1, high mass
resonance decaying to mu+ mu- + X, using a matrix element based likelihood
and a simultaneous measurement of the resonance mass and production rate.
In data with 4.6 fb-1 of integrated luminosity collected by the CDF
detector in p anti-p collisions at s**(1/2) ñ960 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 spi+n-1 resonances, including M > 1071
GeV/c2 at 95% confidence level for a Z' boson with the same couplings
to fermions as the Z boson.
