Whither Hadron Supersymmetry?

TL;DR

The paper discusses evidence for a dynamically broken hadron supersymmetry in QCD, highlighting its implications for meson-baryon relations and the non-observation of certain exotic hadrons, with future research directions.

Contribution

It presents a framework where hadron supersymmetry emerges from QCD and explores its applications and predictions within the constituent quark model.

Findings

Relations between meson and baryon masses confirmed

Predictions that some exotic hadrons should not be observed

Supersymmetry provides a useful tool for understanding hadron spectra

Abstract

A dynamically broken hadron supersymmetry appears to exist as a consequence of QCD. The reasons for the supersymmetry appear most transparently in the framework of the constituent quark model with a diquark approximation to two quarks. Applications of the supersymmetry have led to relations between meson and baryon masses and to predictions that certain kinds of exotic hadrons should not be observed. I summarize the successful applications and discuss possible future directions for this research.
