标题： Scaling Properties of $S$-wave Level Density for Heavy Quarkonium from QCD Sum Rules

摘要： 在QCD求和规则特定方案的框架下，针对重夸克偶素的$S$波态，可以推导出一个表达式，该表达式将夸克偶素态的能量密度与重夸克偶素物理中的普遍特性联系起来，例如重夸克$Q$与介子$(Q\bar q)$之间的质量差以及$(Q\bar Q) \to (Q\bar q) + (\bar Q q)$衰变阈值以下的重夸克偶素态数量。 显示英文摘要

摘要： In the framework of a specific scheme of the QCD sum rules for $S$-wave levels of the heavy quarkonium, one derives an expression, relating the energetic density of quarkonium states and universal characteristics in the heavy quarkonium physics, such as the difference between the masses of a heavy quark $Q$ and meson $(Q\bar q)$ and the number of heavy quarkonium levels below the threshold of $(Q\bar Q) \to (Q\bar q) + (\bar Q q)$ decay.
