Flipped Quartification and a composite $b$-quark

TL;DR

This paper proposes a flipped quartification model with a unique particle assignment, leading to the possibility that the $b$-quark is composite, offering new insights into particle physics structures.

Contribution

It introduces a novel flipped quartification model with a specific particle assignment, enabling the composite nature of the $b$-quark.

Findings

The model contains two standard trinification families and one flipped quartification family.

It suggests the $b$-quark can be composite within this framework.

Provides a new approach to particle family arrangements and quark compositeness.

Abstract

An alternative "flipped" version of the quartification model is obtained by rearrangement of the particle assignments. The model has two standard (trinification) families and one flipped quartification family. An interesting phenomenological implication is that the model allows for a composite $b$-quark.
