%0 Journal Article %T Precision Electroweak Measurements and ``New Physics'' %A William J. Marciano %J Physics %D 1999 %I arXiv %X The status of several precisely measured electroweak parameters is reviewed. Natural relations among them are shown to constrain the Higgs mass, m_H, as well as various ``New Physics'' effects. Indications of an anomalous Zb anti-b coupling are discussed. Constraints on excited W^* bosons are given. %U http://arxiv.org/abs/hep-ph/9902332v1
