Comment on ``Majoron emitting neutrinoless double beta decay in the electroweak chiral gauge extensions''

TL;DR

This paper discusses the implications of implementing a majoron-like scheme within a 331 model, highlighting the necessity of at least three distinct scalar vacuum expectation value scales.

Contribution

It identifies the requirement of multiple scalar vacuum expectation value scales in 331 models with majoron-like schemes.

Findings

At least three different scalar vacuum expectation value scales are necessary.

The analysis clarifies the scalar structure in 331 models with majoron schemes.

Implications for model building and phenomenology in extended gauge theories.

Abstract

We point out that if the majoron-like scheme is implemented within a 331 model, there must exist at least three different mass scales for the scalar vacuum expectation values in the model.
