论文摘要
我们对Nambu - Jona-Lasinio模型（Pauli- villars-villars正则化）中的两电流相关性进行了分析。我们在动量空间中提供明确的表达式，以与夸克顶点中矢量狄拉克双线性的零零分量相对应的两电流相关性，并在晶格上进行了评估。数值结果显示了与最近的晶格数据的显着定性协议。讨论了分解成一体电流的近似值。
We present an analysis of two-current correlations for the pion in the Nambu--Jona-Lasinio model, with Pauli--Villars regularization. We provide explicit expressions in momentum space for two-current correlations corresponding to the zeroth component of the vector Dirac bilinear in the quark vertices, which has been evaluated on the lattice. The numerical results show a remarkable qualitative agreement with recent lattice data. The factorization approximation into one-body currents is discussed.
