Contribution
It provides a comprehensive analysis of electroweak data constraints on the Higgs mass and potential new physics effects, including anomalous couplings and excited bosons.
Findings
Constraints on the Higgs mass from electroweak relations
Evidence of anomalous Zb anti-b coupling
Limits on excited W* bosons
Abstract
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.
