夸克质量密度依赖模型的自洽热力学处理

A consistent thermodynamic treatment for quark mass density-dependent model

Shaoyu Yin, Ru-Keng Su

摘要:

在夸克质量密度依赖模型的热力学处理的模糊性和不一致性进行了处理。提出了一种新的处理方法,以获得自洽的结果。引入了一个新的自变量有效质量,使传统的热力学计算偏导数法仍然适用。讨论了物理真空的贡献。我们发现,在考虑了物理真空的贡献后,夸克质量密度依赖模型给出的奇异夸克物质的性质与MIT袋模型给出的奇异夸克物质的性质基本一致。

英文摘要:

The ambiguities and inconsistencies in previous thermodynamic treatments for the quark mass density-dependent model are addressed. A new treatment is suggested to obtain the self-consistent results. A new independent variable of effective mass is introduced to make the traditional thermodynamic calculation with partial derivative still practicable. The contribution from physical vacuum has been discussed. We find that the properties of strange quark matter given by quark mass density-dependent model are nearly the same as those obtained by MIT bag model after considering the contribution of the physical vacuum.
