The full lepton flavor of little Higgs

TL;DR

This paper reviews the flavor-mixing sources in the little Higgs model with T-parity, highlighting their role in flavor-changing processes and the finiteness of one-loop amplitudes, thus expanding phenomenological understanding.

Contribution

It identifies and discusses previously overlooked flavor-mixing sources in the little Higgs model with T-parity, emphasizing their importance in phenomenology and loop calculations.

Findings

New flavor-mixing sources influence flavor-changing processes.

These sources are necessary for finite one-loop amplitudes.

The review clarifies the phenomenological implications of these sources.

Abstract

The little Higgs model with T-parity, compatible with electroweak precision constraints, introduces new flavor-mixing sources, some of which had been ignored until recently. They are reviewed here, showing that their influence does not only enrich the phenomenology of flavor-changing processes but is also needed to render finite one-loop amplitudes.
