An exact lower bound within a 331 model closing solution

TL;DR

This paper demonstrates that a particular solution to the 331 model's symmetry breaking imposes a lower limit on the vacuum expectation value $v_chi$, which was previously theoretically unconstrained.

Contribution

It provides an exact lower bound on $v_chi$ within a specific 331 model closing solution, clarifying the model's parameter space.

Findings

Establishes a lower bound for $v_chi$

Impacts the parameter constraints of 331 models

Clarifies the relationship between model closure and vacuum expectation values

Abstract

On this note we show how one specific proposal of solution to the problem of `closing' the well motivated 331 model to the Standard Model actually implies a lower bound for the otherwise theoretically free vacuum expectation value $v_\chi$.
