The challenges with the molecular model of the multiquark systems are the identification of the hadronic molecules and the interaction between two color neutral hadrons. We study the di-hadronic molecular systems with proposed interaction potential as s-wave one boson exchange potential along with Screen Yukawa-like potential, and arrived with the proposal that within hadronic molecule the two color neutral hadrons experience the dipole-like interaction. The present study is the continuation of our previous study [1]. With the proposed interaction potential, the mass spectra of ΣsK

The lattice QCD simulation of NJ=ψ and Nη c scattering is performed at m π ≃ 266 MeV in channels with all possible J P. This includes J P ¼ 3=2 AE and 5=2 AE where LHCb discovered P c ð4380Þ and P c ð4450Þ pentaquark states in proton-J=ψ decay. This is the first lattice simulation that reaches the energies 4.3-4.5 GeV where pentaquarks reside. Several decay channels are open in this energy region, and we explore the fate of P c in the one-channel approximation in this work. Energies of eigenstates are extracted for the nucleon-charmonium system at zero total momentum for all quantum numbers, i.e., six lattice irreducible representations. No significant energy shifts are observed. The number of the observed lattice eigenstates agrees with the number expected for noninteracting charmonium and nucleon. Thus, we do not find any strong indication for a resonance or a bound state in these exotic channels within one-channel approximation. This possibly indicates that the coupling of the NJ=ψ channel with other two-hadron channels might be responsible for P c resonances in experiment. One of the challenges of this study is that up to six degenerate J=ψðpÞNð−pÞ eigenstates are expected in the noninteracting limit due nonzero spins of J=ψ and N, and we establish all of them in the spectra.
