# Neutrino Masses and Absence of Flavor Changing Interactions in the 2HDM from Gauge Principles

## TL;DR

This paper introduces Two Higgs Doublet Models augmented with an Abelian gauge symmetry to eliminate flavor-changing neutral currents and generate neutrino masses via the seesaw mechanism, analyzing various experimental constraints.

## Contribution

It presents novel 2HDM frameworks with gauge symmetries that address flavor issues and neutrino mass generation, supported by comprehensive phenomenological analysis.

## Key findings

- Models successfully suppress flavor-changing neutral currents.
- Neutrino masses explained via seesaw mechanism within the models.
- Compatibility with experimental constraints from multiple sources.

## Abstract

We propose several Two Higgs Doublet Models with the addition of an Abelian gauge group which free the usual framework from flavor changing neutral interactions and explain neutrino masses through the seesaw mechanism. We discuss the kinetic and mass-mixing gripping phenomenology which encompass several constraints coming from atomic parity violation, the muon anomalous magnetic moment, rare meson decays, Higgs physics, LEP precision data, neutrino-electron scattering, low energy accelerators and LHC probes.
