We have searched for the production of a neutral gauge boson (Z') with mass above 100 GeV/c2 in ppBAR collisions with the Collider Detector at Fermilab. We present a 95% confidence level (C.L.) limit on the Z' --> mu+-mu- production cross section. We combine the Z' limit with that from our previous dielectron search; the combined result sets a limit of M(z') > 412 GeV/c2 (95% C.L.), assuming standard-model coupling strengths. In addition, the absence of any evidence for an effective muon-quark contact interaction is used to set a lower limit of 1.6 TeV (95% C.L.) on an associated muon-quark compositeness scale.

Abstract

We have searched for the production of a neutral gauge boson (Z') with mass above 100 GeV/c2 in ppBAR collisions with the Collider Detector at Fermilab. We present a 95% confidence level (C.L.) limit on the Z' --> mu+-mu- production cross section. We combine the Z' limit with that from our previous dielectron search; the combined result sets a limit of M(z') > 412 GeV/c2 (95% C.L.), assuming standard-model coupling strengths. In addition, the absence of any evidence for an effective muon-quark contact interaction is used to set a lower limit of 1.6 TeV (95% C.L.) on an associated muon-quark compositeness scale.
