DOI: 10.1088/1674-1137/acc9a2
Abstract: In our previous works, we have analyzed the two-body strong decays of the low-lying $\Omega$ baryon states within a chiral quark model. The results show that the mass, total width, and two body decay $\Omega(2012)… read more here.

DOI: 10.1103/physrevd.98.094018
Abstract: Understanding the hadron spectrum is one of the premier challenges in particle physics. For a long time, the quark model has served as an ordering scheme and brought systematics into the hadron zoo. However, many… read more here.

DOI: 10.1103/physrevlett.128.112001
Abstract: A novel framework is proposed to extract near-threshold resonant states from finite-volume energy levels of lattice QCD and is applied to elucidate structures of the positive parity D_{s}. The quark model, the quark-pair-creation mechanism and… read more here.
