F. J. Botella, G. C. Branco, M. N. Rebelo
TL;DR
This paper extends the concept of Minimal Flavour Violation to multi-Higgs models without Natural Flavour Conservation, analyzing conditions for Higgs couplings to depend solely on the CKM matrix.
Contribution
It introduces a framework for applying MFV to general multi-Higgs models and proposes an expansion for neutral Higgs couplings based on CKM dependence.
Findings
Derived conditions for Higgs couplings to be CKM-dependent
Proposed a new MFV expansion for neutral Higgs interactions
Enhanced understanding of flavour violation in multi-Higgs scenarios
Abstract
We propose an extension of the hypothesis of Minimal Flavour Violation (MFV) to general multi-Higgs Models without the assumption of Natural Flavour Conservation in the Higgs sector. We study in detail under what conditions the neutral Higgs couplings are only functions of and propose a MFV expansion for the neutral Higgs couplings to fermions.
