Flavour Physics in the Littlest Higgs Model with T-Parity: Effects in the K, B_d/s and D systems

TL;DR

This paper investigates the effects of the Littlest Higgs Model with T parity on flavour physics, focusing on the K, B, and D meson systems, revealing potential for large CP violation beyond the Standard Model.

Contribution

It provides a detailed analysis of flavour physics effects in the LHT model, highlighting its potential to produce observable CP violation without conflicting with current experiments.

Findings

Large CP violation possible in the D-sector

Significant effects in K and B systems

Compatibility with existing experimental bounds

Abstract

The Littlest Higgs Model with T parity (LHT) is an interesting alternative model for New Physics at the TeV scale. Although Flavour Physics was not the reason for creating the LHT model, significant effects (such as large CP violation where not predicted by the SM) can be created without violating existing experimental bounds. We study the B-, K- and especially the D-sector.
