Electroweak Precision Data and New Gauge Bosons
Jens Erler
TL;DR
This paper reviews how electroweak precision data constrains the Standard Model Higgs boson and limits on hypothetical Z' gauge bosons, including their mixing effects and implications for flavor and CP violation.
Contribution
It provides a comprehensive analysis of electroweak and low energy data to set bounds on Z' properties and Higgs constraints, highlighting the interplay between precision measurements and new physics.
Findings
Electroweak data strongly limits Z'-Z mixing effects.
Precision measurements constrain Z' exchange amplitudes.
Results restrict flavor and CP violating sectors related to Z'.
Abstract
I review constraints on the Standard Model (SM) Higgs boson from high energy electroweak (EW) precision data. The same data set also strongly limits various mixing effects of hypothetical extra neutral gauge bosons (Z') with the ordinary Z. I also discuss low energy precision measurements which are sensitive to other aspects of Z' physics, such as the direct exchange amplitude and the flavor or CP violating sectors.
