Precision Observables and Electroweak Theories
Jonathan A. Bagger, Adam F. Falk, Morris Swartz
TL;DR
This paper analyzes how precision electroweak measurements constrain alternative theories of electroweak symmetry breaking, showing that models with a cutoff up to 3 TeV are compatible with current data without fine-tuning.
Contribution
It provides bounds on new electroweak theories using precision observables, demonstrating compatibility with high cutoff scales.
Findings
Cutoff as large as 3 TeV is compatible with data
No unnatural fine tuning required for certain models
Constraints on alternative electroweak symmetry breaking theories
Abstract
We compute the bounds from precision observables on alternative theories of electroweak symmetry breaking. We show that a cut-off as large as 3 TeV can be accomodated by the present data, without unnatural fine tuning.
