格点Schwinger模型“介子”波函数的变分研究

Variational Study of“Meson”States in the Lattice Schwinger Model

本文用变分法研究格点Schwinger模型“介子”波函数、计算了矢量和标量介子的质量比、以及矢量介子质量的绝对值,得到与连续理论严格解相近的结果。

We use the variationad method to study the meson states in the lattice Schwinger Model, and to calculate the mass ratio of vector and scalar mesons as well as the mass of vector me- son. Our results are consistent with the exactly values in the continuum.
