介子、重子和核质量的电磁修正
Finite-Volume Electromagnetic Corrections to the Masses of Mesons, Baryons and Nuclei
摘要：
既然格点量子色动力学的计算开始包括QED，那么更好地理解有限体积QED效应是如何改变强子性质的就变得很重要了。与有限体积强相互作用效应的指数行为相反，它们表现出与体积成幂律比例的特性。我们利用描述强子低动量行为的非相对论性有效场论，确定了在体积展开中对介子、重子和原子核质量的有限体积QED修正，其中L是立方体积的空间范围。这推广了以前确定的介子展开，并将其扩展了两个1/L的数量级，以包括强子的电荷半径，磁矩和极化率的贡献。本文对有限体积中μ介子g-2的直接计算进行了观察。
英文摘要：
Now that Lattice QCD calculations are beginning to include QED, it is important to better understand how hadronic properties are modified by finite-volume QED effects. They are known to exhibit power-law scaling with volume, in contrast to the exponential behavior of finite-volume strong interaction effects. We use non-relativistic effective field theories describing the low-momentum behavior of hadrons to determine the finite-volume QED corrections to the masses of mesons, baryons and nuclei out to O(1/L^4) in a volume expansion, where L is the spatial extent of the cubic volume. This generalizes the previously determined expansion for mesons, and extends it by two orders in 1/L to include contributions from the charge radius, magnetic moment and polarizabilities of the hadron. We make an observation about direct calculations of the muon g-2 in a finite volume.
