Interaction and identification of meson-baryon molecule

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 (Rathaud and Rai in Few-Body Syst 60:37, 2019). With the proposed interaction potential, the mass spectra of Sigma K-s*, Sigma K-c*, Sigma K-b*, Sigma D-s*, Sigma D-c*, Sigma D-b*, Sigma B-s*, Sigma B-c*, Sigma B-b*, Xi K-s*,Xi K-c*,Xi K-b*,Xi D-s*,Xi D-c*,Xi D-b*,Xi B-s*,Xi B-c*, Xi bB* meson-baryon molecules are predicted. The Weinberg compositeness theorem which provides a clue for the compositeness of the state is used for determination of the scattering length and effective range. Our results predict some very interesting open as well as hidden flavor near-threshold molecular pentaquark states.

Automated summary

This study explores di-hadronic molecular systems with different interaction potentials and proposes a dipole-like interaction between two color neutral hadrons within hadronic molecules. The results predict some interesting near-threshold molecular pentaquark states.
