A Novel View of Exotic Hadrons and the Covariant ~U(12)-Classification Scheme
Abstract
I classify exotic hadrons into two types, "genuine" and "hidden" exotics, and propose that the "hidden" exotics would be interpreted as "chiralons" in the ~U(12)_SF times O(3,1)_L-classification scheme of hadrons. Based upon this conjecture I investigate the mass spectrum of 1S, 1P, and 2S states for the ccbar system by use of a phenomenological mass formula with the spin-dependent interactions and present possible assignments for exotic neutral charmonium-like states which were recently discovered. It is also mentioned that some J^PC-exotic states predicted in this scheme might correspond to those found in a recent lattice QCD calculation of the charmonium spectrum.
