| 英文摘要 | We study the formation of baryons as composed of quarks and diquarks in hot and dense hadronic matter in a nambu-jona-lasinio (njl)-type model. we first solve the dyson-schwinger equation for the diquark propagator and then use this to solve the dyson-schwinger equation for the baryon propagator. we find that stable baryon resonances exist only in the phase of broken chiral symmetry. in the chirally symmetric phase, we do not find a pole in the baryon propagator. in the color-superconducting phase, there is a pole, but it has a large decay width. the diquark does not need to be stable in order to form a stable baryon, a feature typical for so-called borromean states. varying the strength of the diquark coupling constant, we also find similarities to the properties of an efimov state.
