Precision Electroweak Measurements Circa 2002
Paolo Gambino
TL;DR
This paper reviews precision electroweak measurements around 2002, highlighting anomalies in NuTeV and LEP data, exploring their implications for the Standard Model and potential new physics, especially regarding the Higgs mass.
Contribution
It provides a comprehensive review of the anomalies in electroweak data and discusses possible Standard Model and new physics explanations.
Findings
NuTeV sin^2θ_W measurement deviates by about 3 sigma
LEP FB b quark asymmetries deviate by about 3 sigma
Implications for Higgs mass predictions are discussed
Abstract
Present global fits to electroweak data are characterized by two results that differ from Standard Model expectations by about 3 sigma, the NuTeV measurement of sin^2theta_W and the FB b quark asymmetries measured at LEP. I review possible SM and new physics explanations of these anomalies and the implications for the indirect determination of the Higgs mass.
