A possible global group structure for exotic states

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 X Y Z have been observed recently, we conjecture that the heavy flavors may play an important role in stabilizing the hadronic str...

Description
Summary: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 X Y Z have been observed recently, we conjecture that the heavy flavors may play an important role in stabilizing the hadronic structures beyond the traditional q q ¯ and q q q composites.
