Anomalous Quartic Gauge Couplings from Six Quark Production

TL;DR

This paper explores how anomalous quartic gauge couplings, arising from strong vector boson interactions without a light Higgs, can be probed through six quark production in electron-positron collisions at the ILC.

Contribution

It provides a systematic framework for analyzing anomalous quartic gauge couplings in six quark production processes at future colliders.

Implications for electroweak symmetry breaking models

Abstract

The absence of a light Higgs boson causes vector boson couplings to become strong at 1 TeV. A general framework for a systematic and consistent treatment is provided by effective theories of electroweak symmetry breaking. Already in next-to-leading order there appear quartic gauge couplings that go beyond the standard model and are hence called anomalous. We investigate intermediate three gauge boson states $W^+W^- Z$ and $ZZZ$ occurring in six quark production in electron positron collisions under the conditions of the International Linear Collider. We perform a sensitivity analysis of the relevant anomalous quartic gauge couplings presenting their expected limits.
