“…The form T R of the kinetic energy was suggested in Ref. [35] and used in many models [15,36], while due to our derivation of T R one can establish the connection between the unperturbed RSH H 0 and the RQM, where the same kinetic term is used.…”

The masses of higher DðnLÞ and D s ðnLÞ excitations are shown to decrease due to the string contribution, originating from the rotation of the QCD string itself: it lowers the masses by 45 MeV for L ¼ 2 (n ¼ 1) and by 65 MeV for L ¼ 3 (n ¼ 1). An additional decrease $100 MeV takes place if the current mass of the light (strange) are almost completely unmixed ( ' À1 ), which implies that the mixing angles between the states with S ¼ 1 and S ¼ 0 (J ¼ L) are % 40 for L ¼ 2 and % 42 for L ¼ 3.

“…The mass spectrum of the charmonium family was obtained by solving the Schrödinger equation. The hadron spectroscopy was reconsidered in the framework of quark model [7,8,9,10,11,12,13,14,15,16,17]. In the following, we take the well-known Godfrey-Isgur (GI) quark model as an example and introduce it briefly [17].…”

The hidden-charm pentaquark and tetraquark states

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.

RMS and charge radii in a potential model

The Dalgarno's method of perturbation is used to solve the Schrodinger's equation with the Cornell potential V (r) = − 4αs 3r + br + c. The short range and long range effect of the potential is incorporated in the same wave function by using two scales r S and r L as an integration limit. With the wave function then the results for bounds on r.m.s. radii of various heavy flavored mesons are reported. We have also showed the relation between r.m.s. and charge radius of mesons.
