关于含一个重夸克强子的中等质量的注记

Remark on in-medium masses of hadrons with one heavy quark

Mariusz Sadzikowski

摘要:

在这篇短文中,我们导出了一个描述含有单个重夸克的强子的质量与热浴温度关系的公式。它采取一个简单的标度形式,其指数与轻强子的情况不同。推导是基于袋模型范式的框架内的尺寸参数。这个场景的简单实现是针对MIT袋模型的。本文给出了赝标介子和矢量介子($D, D^\ast$或$B, B^\ast$)之间的质量分裂随温度的变化。

英文摘要:

In this short note we derive a formula which describes the dependence of the mass of a hadron which contains a single heavy quark on the temperature of the heat bath. It takes a simple scaling form with the exponent which is different than in the case of the light hadrons. The derivation is based on dimensional arguments within the framework of the bag model paradigm. The simple realization of this scenario is presented for the MIT bag model. The mass splitting between pseudoscalar and vector mesons ($D, D^\ast$ or $B, B^\ast$) as a function of temeperature is presented.
