Lepton Flavour Violating Decays in the Littlest Higgs Model with T-Parity

TL;DR

This paper analyzes lepton flavor violating decays within the Littlest Higgs model with T-parity, highlighting potential observable effects due to the model's enhanced violation signals compared to the Standard Model.

Contribution

It provides the first extensive analysis of lepton flavor violation in the LHT model, emphasizing its potential detectability in upcoming experiments.

Findings

LHT predicts significantly larger lepton flavor violation than the Standard Model.

Potential for near-future experimental detection of LHT-induced lepton flavor violation.

Enhanced decay rates could serve as signals for new physics beyond the Standard Model.

Abstract

We present the results of an extensive analysis of lepton flavour violating decays in the Littlest Higgs model with T-parity (LHT). As lepton flavour violation is highly suppressed in the Standard Model by small neutrino masses, the LHT effects turn out to be naturally huge and could be seen in the near future experiments.
