带有质量的Wilson费米子的格点Schwinger模型中M_V对m的变化率的计算

The Calculation of M_v/m in the Lattice Schwinger Model with Massive Wilson Fermions

用变分法计算带有质量的Ｗｉｌｓｏｎ费米子的格点Ｓｃｈｗｉｎｇｅｒ模型中矢量介子的质量Ｍ，从而求出Ｍ、对费米子质量ｍ的变化率Ｍｖ／ｍ（ｍ＝０处），结果与连续理论的准确解十分接近．

Using the variational method, we calculate the vector meson mass Mv in the Lattice Schwinger model with massive Wilson fermions, and then calculate the rate of change of the vector meson mass M. with the fermion mass m(at m = 0). Our results are consistent with the exact value in the continuum.
