Lepton Flavour Violation in Hadron Decays of the Tau Lepton in the Simplest Little Higgs Model

TL;DR

This paper investigates lepton flavor violating decays of the tau lepton into hadrons within the Simplest Little Higgs model, predicting extremely suppressed branching ratios far below current experimental limits.

Contribution

It provides the first detailed analysis of tau lepton hadron decays with lepton flavor violation in the Simplest Little Higgs model, estimating their branching ratios.

Findings

Branching ratios are at least four orders of magnitude below experimental bounds.

The model predicts very suppressed lepton flavor violating decay rates.

Results suggest such decays are unlikely to be observed with current experiments.

Abstract

We study Lepton Flavour Violating hadron decays of the tau lepton within the Simplest Little Higgs model. Namely we consider $\tau \rightarrow \mu (P, V, PP)$ where $P$ and $V$ are short for a pseudoscalar and a vector meson. We find that, in the most positive scenarios, branching ratios for these processes are predicted to be, at least, four orders of magnitude smaller than present experimental bounds.
