Off-peak lepton asymmetries from new Z's

Neutral heavy gauge bosons have characteristic vector and axial-vector couplings to quarks and leptons. The hadronic process pp→(γ/sup */,Z0/sup */,. . .)+...→l-l++..., where l = e,μ,tau, exhibits characteristic forward-backward asymmetries whenever the lepton pair is not at rest in the pp center of mass. These asymmetries can be used to probe the couplings of a new boson. Attention is paid to such asymmetries for dilepton masses in the interference region between the new boson and the Z0
