Description
We propose a means to discriminate between the two basic variants of Little Higgs
models, the Product Group and Simple Group models, at the next generation of
colliders. It relies on a special coupling of light pseudoscalar particles present in
Little Higgs models, the pseudo-axions, to the Z and the Higgs boson, which is
present only in Simple Group models. We discuss the collider phenomenology of the
pseudo-axion in the presence of such a coupling at the LHC, where resonant production
and decay of either the Higgs or the pseudo-axion induced by that coupling can be
observed for much of parameter space. The full allowed range of parameters, including
regions where the observability is limited at the LHC, is covered by a future ILC,
where double scalar production would be a golden channel to look for.
