The Spectrum of $P$-Wave Hidden-Charm Exotic Mesons in the Diquark Model

14 Apr 2020 Giron Jesse F. Lebed Richard F.

We study the fine structure in the spectrum of known and predicted negative-parity hidden-charm exotic meson states, which comprise the lowest $P$-wave multiplet in the dynamical diquark model. Starting with a form previously shown to successfully describe the $S$-wave states, we develop a 5-parameter Hamiltonian that includes spin-orbit and tensor terms... (read more)
