A null hypothesis test of the standard model allows the extraction $\sin^2θ_W^{νN}(\equiv 1-M_W^2/M_Z^2)=0.2277\pm0.0013(stat)\pm0.0009(syst)$, a value that differs from predictions of global electroweak fits by $+3.0σ$.To appear in Proceedings of "QCD and High Energy Interactions", 2002 Recontres de MoriondHigh Energy Physics - Experimenttext
