论文摘要
我们研究了SU $（4 | 1）$部分压抑的手性扰动理论的pion-kaon散射幅度的贡献。将其与有限体积分析相结合，我们证明了对易于计算的连接相关函数的晶格计算能够提供有价值的噪声相关功能的有价值的信息，并可以作为对相应晶格技术的未来改进的理论指导。
We study the contributions from the connected and disconnected contraction diagrams to the pion-kaon scattering amplitude within the framework of SU$(4|1)$ partially-quenched chiral perturbation theory. Combining this with a finite-volume analysis, we demonstrate that a lattice calculation of the easier computable connected correlation functions is able to provide valuable information of the noisier disconnected correlation functions, and may serve as a theory guidance for the future refinement of the corresponding lattice techniques.
