Abstract

We update our previous global analysis of weak neutral current and Z and W data in which the parameters hV and hA associated with new heavy physics were constrained, by incorporating recent results on Z properties and MW. We obtain 0.93<hV<0.33, 1.9<hAZ<0.27, and 2.5<hAW<1.5 at 90% C.L., considerably better than the previous limits.
