格点量子色动力学中的粲偶素和奇异粒子

Charmonium and exotics from lattice QCD

Francesco Knechtli

摘要:

我们审查选定的晶格结果的粲谱和第一次尝试寻找奇异状态的存在。强子-夸克偶素模型被提出来解释强子内部的夸克偶素核中的一些奇异态。本文对静态夸克极限下的强子-夸克偶素模型进行了晶格研究。粲夸克在低能观测量和粲偶素结合能中的作用。在模型计算中,我们能够评估在连续介质中的粲夸克的去耦的修正。

英文摘要:

We review selected lattice results on the charmonium spectrum and first attempts to search for the existence of exotic states. The hadro-quarkonium model was proposed to interpret some of the exotic states as a quarkonium core inside a hadron. We present a lattice study of the hadro-quarkonium model in the limit of static quarks. The charm quark decouples in low energy observables and binding energies of charmonium. In a model calculation we are able to evaluate the corrections to decoupling of the charm quark in the continuum.
