The electroweak chiral Lagrangian reanalyzed
Andreas Nyffeler, Andreas Schenk
In this paper we reanalyze the electroweak chiral Lagrangian with particular focus on two issues related to gauge invariance. Our analysis is based on a manifestly gauge-invariant…
Gauge-invariant Green's functions for the bosonic sector of the standard model
Andreas Nyffeler, Andreas Schenk
There are many applications in gauge theories where the usually employed framework involving gauge-dependent Green's functions leads to considerable problems. In order to overcome…
A Manifestly Gauge-Invariant Approach to Charged Particles
A. Schenk
In this article we provide a manifestly gauge-invariant approach to charged particles. It involves (1) Green functions of gauge-invariant operators and (2) Feynman rules which do n…
Effective Field Theory for a Heavy Higgs Boson: Matching and Gauge Invariance
A. Nyffeler, A. Schenk
For large values of the Higgs mass the low energy structure of the gauged linear sigma model in the spontaneously broken phase can adequately be described by an effective field the…
Effective Field Theory for a Heavy Higgs: a Manifestly Gauge Invariant Approach
A. Nyffeler, A. Schenk
For large values of the Higgs boson mass the low energy structure of the gauged linear sigma model in the spontaneously broken phase can adequately be described by an effective fie…
Effects of Top Compositeness
Howard Georgi, Lev Kaplan, David Morin +1
We investigate the effects of top quark compositeness on various physical parameters, and obtain lower limits on the compositeness scale from electroweak precision data. We conside…
