摘要

手性对称性及其自发破缺在轻强子和重强子系统中都起着重要的作用。手性微扰理论是量子色动力学的低能量有效场论。在这项工作中,我们将回顾在χPT框架内对重介子和重子性质的手性修正的研究。我们还将回顾轻伪标量介子和重强子的散射,通过它们可以理解许多新的共振,如Ds0 *(2317)。此外,在过去的几十年里,许多新的强子态被实验观察到。这些态中有很大一部分是近阈值共振,如带电的类粲态Zc和Zcs态、类底粲态Zb态、隐藏粲五夸克态Pc和Pcs态以及双粲态Tcc态等。它们是由一对迷住(底部)强子组成的松散束缚分子态的很好的候选者,这与松散束缚的氘核非常相似。现代核力是建立在手性有效场论(χEFT)的基础上的,它是将χPT推广到具有两个物质场的体系。两个核子之间的远程和中远程相互作用分别来自于单介子交换和双介子交换,它们受到手性对称性及其自发破缺的约束。短距离相互作用可以用低能常数来描述。这种框架对核子-核子散射和核子非常有效。在这项工作中,我们将在χEFT的框架内对重强子分子状态的进展进行广泛的回顾。我们要强调的是,同样的手性动力学不仅支配着原子核和氘核的形成,而且也支配着由两个重强子组成的浅界态或共振。

Chiral perturbation theory for heavy hadrons and chiral effective field theory for heavy hadronic molecules

Chiral symmetry and its spontaneous breaking play an important role both in the light hadron and heavy hadron systems. The chiral perturbation theory (χPT) is the low energy effective field theory of the Quantum Chromodynamics. In this work, we shall review the investigations on the chiral corrections to the properties of the heavy mesons and baryons within the framework of χPT. We will also review the scatterings of the light pseudoscalar mesons and heavy hadrons, through which many new resonances such as the Ds0(2317) could be understood.

Moreover, many new hadron states were observed experimentally in the past decades. A large group of these states is near-threshold resonances, such as the charged charmoniumlike Zc and Zcs states, bottomoniumlike Zb states, hidden-charm pentaquark Pc and Pcs states and the doubly charmed Tcc state, etc. They are very good candidates of the loosely bound molecular states composed of a pair of charmed (bottom) hadrons, which are very similar to the loosely bound deuteron. The modern nuclear force was built upon the chiral effective field theory (χEFT), which is the extension of the χPT to the systems with two matter fields. The long-range and medium-long-range interactions between two nucleons arise from the single- and double-pion exchange respectively, which are well constrained by the chiral symmetry and its spontaneous breaking. The short-distance interactions can be described by the low energy constants. Such a framework works very well for the nucleon–nucleon scattering and nuclei. In this work, we will perform an extensive review of the progress on the heavy hadronic molecular states within the framework of χEFT. We shall emphasize that the same chiral dynamics not only govern the nuclei and forms the deuteron, but also dictates the shallow bound states or resonances composed of two heavy hadrons.

期刊介绍: Physics Reports keeps the active physicist up-to-date on developments in a wide range of topics by publishing timely reviews which are more extensive than just literature surveys but normally less than a full monograph. Each report deals with one specific subject and is generally published in a separate volume. These reviews are specialist in nature but contain enough introductory material to make the main points intelligible to a non-specialist. The reader will not only be able to distinguish important developments and trends in physics but will also find a sufficient number of references to the original literature.
