夸克模型中的重介子

Heavy mesons in the Quark Model

D. R. Entem, P. G. Ortega, J. Segovia, F. Fernández

摘要:

自从发现$J/ψ$以来,夸克模型在描述仅含$q\bar q$组分的重介子的光谱和性质方面取得了很大的成功。然而,自2003年以来,随着$X(3872)$的发现,人们发现了许多在朴素夸克模型中无法容纳的态,使得在重介子态中包含更高的Fock分量成为不可避免的。我们将概述重介子的夸克模型的成功,并指出一些可能是更复杂结构的状态,如介子-介子分子。

英文摘要:

Since the discovery of the $J/ψ$, the quark model was very successful in describing the spectrum and properties of heavy mesons including only $q\bar q$ components. However since 2003, with the discovery of the $X(3872)$, many states that can not be accommodated on the naive quark model have been discovered, and they made unavoidable to include higher Fock components on the heavy meson states. We will give an overview of the success of the quark model for heavy mesons and point some of the states that are likely to be more complicated structures such as meson-meson molecules.
