摘要：

We update our previous global analysis of weak neutral current and Z and W data in which the parameters h(V) and h(A) associated with new heavy physics were constrained, by incorporating recent results on Z properties and M(W). We obtain -0.93 < h(V) < 0.33, -1.9 < h(AZ) < 0.27, and -2.5 < h(AW) < 1.5 at 90% C.L., considerably better than the previous limits.
