有限温度和密度下手征孤子模型中重子质量的计算

The baryon mass calculation in the chiral soliton model at finite temperature and density

Hui Zhang, Renda Dong, Song Shu

摘要:

在平均场近似下,我们研究了热介质中的手征孤子模型。本文对热介质中的孤子能量和重子质量进行了详细的计算,并强调指出,为了从热背景中导出有限的重子质量,必须对孤子能量中的热有效势进行适当的处理。给出了手征孤子模型在有限温度和密度下重子质量的计算结果。

英文摘要:

In the mean-field approximation, we have studied the soliton which is embedded in a thermal medium within the chiral soliton model. The energy of the soliton or the baryon mass in the thermal medium has been carefully evaluated, in which we emphasize that the thermal effective potential in the soliton energy should be properly treated in order to derive a finite and well-defined baryon mass out of the thermal background. The result of the baryon mass at finite temperatures and densities in chiral soliton model are clearly presented.
