ResumoA precise measurement of the Z mass at SLC and LEP can provide information on the mass of a new neutral gauge boson, guiding its detection at hadron colliders. For a significant range of parameters the decay rate of the new Z into W+W− is greater than the one into e+e− (μ+μ−, τ+ μ−), giving rise to a new signature. We discuss these two issues in detail for E6 superstring-inspired models.
