N2 - The mixing of a new Z′ boson with the Z significantly improves the fit to the LEP precision electroweak data, provided that the Z′ couples mainly to quarks. If MZ2 < 200 GeV, the s-channel Z2 production and (W, Z, γ) Z2 pair production cross sections at the Tevatron give an excess above QCD of bb̄ and (W, Z, γ) bb̄ events, respectively, with invariant mass m(bb̄) ≈ MZ2, which provide viable signals for detection of the Z2. The interference of the Z2 with γ, Z1 in e+e- → b̄b (c̄c) at LEP 1.5 energies is correlated with Rb (Rc) and may be observable.
