标题： Quarkonium Spectroscopy and Perturbative QCD: A New Perspective

摘要： 我们报告了重夸克偶素物理最近理论进展的新方面。 (1) 与普遍信念相反，基于微扰QCD的非相对论束缚态理论能够很好地描述底夸克偶素谱的粗结构。 (2) 这导致了底夸克偶素态的新物理图景：束缚态质量主要由束缚态内部b和bbar的自能累积组成。 (3) 提供了与传统现象学势模型方法的联系。 显示英文摘要

摘要： We report new aspects of the recent theoretical progress in heavy quarkonium physics. (1) Contrary to wide beliefs, the gross structure of the bottomonium spectrum is described well by the non-relativistic boundstate theory based on perturbative QCD. (2) This leads to a new physical picture of the bottomonium states: the boundstate mass is composed mainly of the self-energies of b and bbar accumulated inside the boundstate. (3) A connection to the conventional phenomenological potential-model approaches is provided.
