论文摘要
我们提出了一种形式主义，描述了有限体积的两$π^+$和三$π^+$动力学，形式主义是基于变异方法和faddeev方法的组合。演示文稿中都包括配对和三体相互作用。还讨论了有限晶格间距和立方晶格对称性的影响。为了说明形式主义的应用，与手学有效理论中领先的相互作用项相似的成对接触相互作用用于分析最近的晶格结果。
We present a formalism to describe two-$π^+$ and three-$π^+$ dynamics in finite volume, the formalism is based on combination of a variational approach and the Faddeev method. Both pair-wise and three-body interactions are included in the presentation. Impacts of finite lattice spacing and the cubic lattice symmetry are also discussed. To illustrate application of the formalism, the pair-wise contact interaction that resembles the leading order interaction terms in chiral effective theory is used to analyze recent lattice results.
