Light Pseudoscalars in Little Higgs Models at the ILC

TL;DR

This paper explores the characteristics of light pseudoscalar particles in Little Higgs models and proposes a method to distinguish model classes at the ILC based on specific production and decay signatures.

Contribution

It introduces a novel approach to differentiate between product and simple group Little Higgs models using pseudoscalar particle phenomenology at the ILC.

Findings

Identification of production channels unique to simple group models.

Decay modes that are forbidden in product group models.

A proposed experimental method for model discrimination.

Abstract

We discuss the properties of light pseudoscalar particles, the so-called pseudoaxions, within Little Higgs models, focusing on their phenomenology at the ILC. We especially discuss a method of how to distinguish between the two basic classes of Little Higgs models, the product and simple group models, by a specific production channel and decay mode. These are strictly forbidden in the product group models.
