论文摘要
大型相关函数在从欧几里得晶格场理论中提取粒子质量中具有关键作用，但是对这些数量的统计特性知之甚少。在这项工作中，针对具有独特的间隙真空的玻感相互作用晶格场理论，确定了消失动量时相关函数分布的渐近形式。证明可以利用大欧几里得时代的渐近形式的偏差来确定理论的光谱。
Large-time correlation functions have a pivotal role in extracting particle masses from Euclidean lattice field theory calculations, however little is known about the statistical properties of these quantities. In this work, the asymptotic form of the distributions of the correlation functions at vanishing momentum is determined for bosonic interacting lattice field theories with a unique gapped vacuum. It is demonstrated that the deviations from the asymptotic form at large Euclidean times can be utilized to determine the spectrum of the theory.
