Muon Magnetic Moment and Lepton Flavor Violation in the Economical 3-3-1 Model

TL;DR

This paper calculates contributions of the economical 3-3-1 model to the muon magnetic moment and lepton flavor violation, deriving bounds on the model's symmetry breaking scale and exploring potential signals in upcoming experiments.

Contribution

It provides the first comprehensive analysis of muon g-2 and lepton flavor violation within the economical 3-3-1 model, linking experimental bounds to model parameters.

Findings

Lower bounds on the symmetry breaking scale are established.

Potential for observable $$ decay signals remains in future experiments.

Current experimental limits constrain but do not exclude the model's parameter space.

Abstract

In this work we compute all relevant contributions stemming from the economical 3-3-1 model to the muon magnetic moment and the lepton flavor violation decay $\mu \rightarrow e\gamma$. Using the current bounds on these phenomena, we derive lower limits on the scale of symmetry breaking of the model. Moreover, taking into account existing limits from meson and collider studies we show that there is still room for a possible signal in $\mu \rightarrow e\gamma$ in the near future.
