The dynamic mechanism of short range interactions between u/d quarks remains an open and challenging problem.In order to reveal this quark dynamics,we perform a systematic analysis of N N,D_(03),and D_(30)systems in t...

Hexaquarks constitute a natural extension of complex quark systems,just as tetra-and pentaquarks do.To this end,the current status of d^(*)(2380)in both experiment and theory is reviewed.Recent high-precision meas-ure...

In the framework of the constituent quark model, the possible S-wave heavy dibaryon states with the c flavor are investigated. The factors which are responsible for the binding behavior of the dibaryon system are anal...

We study the structures of NΩ and △Ω systems in the extended chiral SU(3) quark model by solving a resonating group method equation. The results show that both systems are weakly bound states and changed into unb...
