“…The delocalization parameter is determined by the dynamics of the interacting quark system, and it thus allows the quark system to choose the most favorable configuration through its own dynamics in a larger Hilbert space. The model gives a good description of nucleon-nucleon and hyperonnucleon interactions and the properties of the deuteron [24][25][26][27][28]. It is also employed to calculated the baryon-baryon scattering phase shifts and the dibaryon candidates in the framework of the resonating group method (RGM) [29][30][31].…”

Inspired by the discovery of two pentaquarks P c (4380) and P c (4450) at the LHCb detector, we study possible hidden-charm molecular pentaquarks in the framework of quark delocalization color screening model. Our results suggest that both N η c with IJ P = is a resonance, it may not be a good candidate of the observed P c (4450) because of the opposite parity of the state to P c (4380), although the mass of the state is not far from the experimental value. In addition, the calculation is extended to the hidden-bottom pentaquarks, and similar properties to that of hidden-charm pentaquarks system are obtained.

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.

“…This "inevitable" dibaryon has been extensively studied in our group [4,8,9]. To provide more theoretical input for experimental search, we included IJ P = 03 + ∆∆ channel coupling to the N N D-wave scattering phase shifts calculation and a resonance at E c.m.…”

Inspired by the discovery of the dibaryon d * and the experimental search of N Ω dibaryon with the STAR data, we study the strange dibaryon N Ω further in the framework of quark delocalization color screening model and chiral quark model. We have shown N Ω is a narrow resonance in ΛΞ D-wave scattering before. However, the Λ-Ξ scattering data analysis is quite complicated. Here we calculate the low-energy N Ω scattering phase shifts, scattering length, effective range and binding energy to provide another approach of STAR data analysis. Our results show there exists an N Ω "bound" state, which can be observed by the N -Ω correlation analysis with RHIC and LHC data, or by the new developed automatic scanning system at J-PARC. Besides, we also find that the hidden color channel-coupling is important for the N Ω system to develop intermediate-range attraction.
