摘要

讨论了有效模型在描述重子和奇异重子与介子之比行为方面的适用性。在EPNJL模型的框架中,Bethe-Salpeter方程被用来寻找重子的质量,这些重子被认为处于双夸克-夸克状态。讨论了在有限化学势下重子的熔化,并指出了重子分解温度的风味依赖性。证明了有限化学势下的双夸克-夸克态的描述由于玻色凝聚的存在而受到限制。这种效应在轻重夸克和重子的描述中得到了强烈的体现。Λ0/π+和Ξ−/π+比值作为T/μB变量的函数表现出明显的行为,其中T和μB是沿着熔化线计算的。

Diquarks and Λ0/π+, Ξ−/π+ Ratios in the Framework of the EPNJL Model
The applicability of the effective models to the description of baryons and the behaviour of ratios of strange baryons to pions is discussed. In the framework of the EPNJL model, the Bethe–Salpeter equation is used to find masses of baryons, which are considered to be in a diquark-quark state. Baryon melting is discussed at a finite chemical potential, and a flavor dependence of the hadronic deconfinement temperature is pointed out. It is shown that the description of the diquark-quark state at finite chemical potential is limited due to the occurrence of Bose condensate. This effect is strongly manifested in the description of light diquarks and baryons. Both the Λ0/π+ and Ξ−/π+ ratios show a sharp behaviour as functions of the T/μB variable, where T and μB are calculated along the melting lines.
