Can Family Gauge Bosons Be Visible by Terrestrial Experiments?

TL;DR

This paper explores the potential for detecting family gauge bosons in terrestrial experiments, proposing an extended model that predicts a gauge boson with a mass around 4.3 TeV.

Contribution

It introduces an extended U(3) family gauge symmetry model that predicts a potentially observable gauge boson at collider energies.

Findings

Predicts a family gauge boson with mass ~4.3 TeV

Suggests possible detection in future terrestrial experiments

Extends Sumino's family gauge boson model

Abstract

It is investigated whether observations of family gauge bosons by terrestrial experiments are possible or not. We propose an extended version of Sumino's family gauge boson model based on U(3) family symmetry. Then, we can expect the lowest family gauge boson $A_1^1$ with $M \sim 4.3$ TeV.
