Abstract

This article delves into the application of Dimer images in addressing two-body problems within lattice quantum chromodynamics (LQCD), providing the finite volume energy spectrum of deuterons in the context of S13-D13 coupled-channels. The author commences by introducing the Dimer-particle method and formulating the Lagrangian for the scattering of two fermions. Additionally, the author defines the relativistic high partial zeta-function in a moving reference system and outlines a method for its rapid convergence calculation. The article further scrutinizes zeta-function representations across various momentum shells and discusses issues related to symmetry breakdown in specific momentum configurations. In sum, this work presents innovative methods for incorporating spin and isospin indices into dimer models, thereby establishing closer relevance to LQCD and deuteron studies.

有限体积中的氘核系统与粒子二聚体图像
本文深入探讨了二聚体图像在解决格子量子色动力学(LQCD)中两体问题时的应用,提供了 S13-D13 耦合通道背景下氘核的有限体积能谱。作者首先介绍了二聚粒子方法,并制定了两个费米子散射的拉格朗日。此外,作者还定义了移动参考系中的相对论高部分zeta函数,并概述了其快速收敛计算的方法。文章进一步仔细研究了各种动量壳的zeta函数表示,并讨论了特定动量配置中与对称性破坏有关的问题。总之,这项工作提出了将自旋和等时性指数纳入二聚体模型的创新方法,从而与 LQCD 和氘核研究建立了更密切的联系。
