We present calculations of the cross-sections and the forward-backward asymmetry forp $$\bar p$$ →ℓ+ ℓ− +X in the framework of anSU(2)×U(1)×G model with two neutral gauge bosons [G=U(1) orSU(2)]. It is shown that a peak in the cross-section associated with a large asymmetry will characterize a deviation from the standard model.
