論文簡介

The adiabatic effective baryon-baryon interactions and dibaryon candidates are studied syst ematicallywith three constituent quark models based on different effective degrees of freedom: Glozman-Riska-Brown Goldstoneboson exchange model based on constituent quark and Goldstone boson coupling; Fujiwara model based on constituentquark gluon coupling and Nijmegen one-boson exchange; QDCSM based on constituent quark and gluon coupling withquark delocalization and color screening. We find that the three models predicted the similar effective baryon-baryoninteractions for roughly two thirds among the 64 states consisted of octet and decuplet baryons. The differences amongthree models and their separate characteristics are also studied.
