Resumo

We study the constraints on the minimal (gauge) extension of the standard model from ν-q neutral current data. Using α, Gμ and MZ (with the present accuracy) as input parameters, we find that previous bounds on MZ′ are strengthened by ∼ 10% [MZ′>555 GeV (90% CL) for mt>77 GeV and mH < 1 TeV, for the simplest model].
