“…Our calculation does not exclude a possible mixture of standard charmonium states in the channels where we have found attractive molecular systems. This admixture could explain some properties of the X(3872) [17,18]. We would like to emphasize the similarity of our results to those of Ref.…”

“…In Ref. [783], Gershtein, Likhoded, and Luchinsky systematically studied heavy quarkonia from Regge trajectories on (n, M 2 ) and (M 2 , J) planes, and interpreted the Y(3940) as the χ c0 (2P) charmonium state. This was further discussed combining the linearity and parallelism of Regge trajectories with a hyperfine splitting relation in multiplet in Ref.…”

The hidden-charm pentaquark and tetraquark states

et al. 2016

In the past decade many charmonium-like states were observed experimentally. Especially those charged charmoniumlike Z c states and bottomonium-like Z b states can not be accommodated within the naive quark model. These charged Z c states are good candidates of either the hidden-charm tetraquark states or molecules composed of a pair of charmed mesons. Recently, the LHCb Collaboration discovered two hidden-charm pentaquark states, which are also beyond the quark model. In this work, we review the current experimental progress and investigate various theoretical interpretations of these candidates of the multiquark states. We list the puzzles and theoretical challenges of these models when confronted with the experimental data. We also discuss possible future measurements which may distinguish the theoretical schemes on the underlying structures of the hidden-charm multiquark states.

By applying the Bohr-Sommerfeld quantization approach to the quadratic form of the spinless Salpeter-type equation (QSSE), we show that the obtained Regge trajectories for the mesons consisting of unequally massive quarks take the form M 2 = β (c l l + π n r + c 0 )2/3 + c 1 , which have the same form as the Regge trajectories for charmonia and bottomonia. Then we apply the obtained Regge trajectories to fit the spectra of the strange mesons, the heavy-light mesons (the D, D s , B and B s mesons) and the bottom-charmed mesons. The fitted Regge trajectories are in agreement with the experimental data and the theoretical predictions, which demonstrates that the newly proposed Regge trajectories can be applied universally to the light mesons, the heavy-light mesons and the heavy mesons. By fitting the spectra of the mesons composed of different quarks, the concavity of these Regge trajectories are illustrated, which is of cardinal significance for the potential models.
