Invariants and Flavour in the General Two Higgs Doublet Model (Moriond QCD2013)

TL;DR

This paper develops weak basis invariants for the general Two Higgs Doublet Model to analyze flavor physics implications regardless of basis choice.

Contribution

It introduces basis-invariant quantities that help interpret flavor models within the 2HDM framework, enhancing understanding of flavor physics.

Findings

Invariants provide basis-independent insights into flavor structure.

Method applicable to arbitrary weak basis transformations.

Facilitates comparison of different flavor models.

Abstract

We construct weak basis invariants which can give insight into the physical implications of any flavour model, written in an arbitrary weak basis (WB) in the context of 2HDM.
