A possible global group structure for exotic states

TL;DR

This paper hypothesizes that heavy flavors could be crucial in stabilizing exotic hadronic states, inspired by the non-observation of certain pentaquarks and recent discoveries of other exotic particles.

Contribution

It proposes a new perspective on the role of heavy flavors in the stability of exotic hadronic states beyond traditional quark models.

Findings

Heavy flavors may stabilize exotic states.

Non-observation of certain pentaquarks suggests alternative structures.

Recent observations support the importance of heavy flavors in exotic hadron stability.

Abstract

Based on the fact that the long expected pentaquark which possesses the exotic quantum numbers of $B=1$ and $S=1$ was not experimentally found, although exotic states of $XYZ$ have been observed recently, we conjecture that the heavy flavors may play an important role in stabilizing the hadronic structures beyond the traditional $q\bar q$ and $qqq$ composites.
