Topcolor-Assisted Supersymmetry

TL;DR

This paper proposes a model combining topcolor and supersymmetry with gauge-mediated breaking to naturally produce a squark mass pattern that suppresses flavor-changing neutral currents, aligning with experimental constraints.

Contribution

It introduces a novel supersymmetric topcolor extension with gauge mediation that achieves the desired squark mass degeneracy and heaviness, addressing flavor issues.

Findings

Achieves degenerate first-two-generation squark masses at the weak scale.

Generates a heavy third-generation squark to suppress flavor-changing processes.

Provides a consistent framework for supersymmetry and topcolor integration.

Abstract

It has been known that the supersymmetric flavor changing neutral current problem can be avoided if the squarks take the following mass pattern, namely the first two generations with the same chirality are degenerate with masses around the weak scale, while the third generation is very heavy. We realize this scenario through the supersymmetric extension of a topcolor model with gauge mediated supersymmetry breaking.
