原子物理学和强子物理学的共同要素

The Common Elements of Atomic and Hadronic Physics

Stanley J. Brodsky

摘要:

原子物理学和强子物理学都是由杨米尔斯规范理论拉格朗日量所支配的;事实上,阿贝尔量子电动力学可以被看作是量子色动力学的零色极限。我回顾了原子物理学的技术可以提供重要的洞察强子本征态QCD的一些领域。例如,预言类氢原子光谱和结构的狄拉克-库仑方程,在强子物理学中有一个类似的形式,即与光阵面全息一致的与标架无关的光阵面相对论运动方程,它给出了轻强子光谱、动力学和结构的显著一级近似。飞行中反氢的产生可以在振幅水平上提供对QCD中强子产生动力学的重要认识。运行耦合的重整化标度在QED中是明确设定的;类似的程序在QCD中设定重整化标度,导致与方案无关的标度固定预言。相反,强子物理学中的许多方法,如标度律、演化方程、夸克交换过程和光阵面量子化,在原子物理学和光子科学中,特别是在相对论领域,也有重要的应用。

英文摘要:

Atomic physics and hadronic physics are both governed by the Yang Mills gauge theory Lagrangian; in fact, Abelian quantum electrodynamics can be regarded as the zero-color limit of quantum chromodynamics. I review a number of areas where the techniques of atomic physics can provide important insight into hadronic eigenstates in QCD. For example, the Dirac-Coulomb equation, which predicts the spectroscopy and structure of hydrogenic atoms, has an analog in hadron physics in the form of frame-independent light-front relativistic equations of motion consistent with light-front holography which give a remarkable first approximation to the spectroscopy, dynamics, and structure of light hadrons. The production of antihydrogen in flight can provide important insight into the dynamics of hadron production in QCD at the amplitude level. The renormalization scale for the running coupling is unambiguously set in QED; an analogous procedure sets the renormalization scales in QCD, leading to scheme-independent scale-fixed predictions. Conversely, many techniques which have been developed for hadron physics, such as scaling laws, evolution equations, the quark-interchange process and light-front quantization have important applicants for atomic physics and photon science, especially in the relativistic domain.
