Abstract
We present a search for a new narrow, spin-1, high mass resonance decaying to μ+μ-+X [mu superscript + mu superscript - + 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 [fb superscript -1] of integrated luminosity collected by the CDF detector in pp̅ collisions at √s=1960 [square root of 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/c2 [GeV / c superscript 2] at 95% confidence level for a Z′ [Z prime] boson with the same couplings to fermions as the Z boson.
