Multiple point principle as a mechanism for the suppression of FCNC and CP--violation phenomena in the 2HDM

TL;DR

This paper proposes using the multiple point principle to naturally suppress flavor-changing neutral currents and CP violation in the two Higgs doublet model, offering a new theoretical approach to Higgs phenomenology.

Contribution

It introduces a novel application of the multiple point principle to address CP conservation and FCNC suppression in the 2HDM.

Findings

MPP can ensure CP conservation in 2HDM

FCNC are suppressed via MPP constraints

Higgs phenomenology is consistent with MPP assumptions

Abstract

We argue that multiple point principle (MPP) can be used to ensure CP conservation and the absence of flavour changing neutral currents within the two Higgs doublet model (2HDM). We also discuss Higgs phenomenology in the MPP inspired 2HDM.
