标题： Residual mass effects in improved domain wall fermions

摘要： 为了改进使用域墙费米子（DWFs）的模拟，建议投影出生成DWF转移矩阵的4维狄拉克算子的若干低本征值。我们研究这种投影方法如何影响冻结DWF的手征性质。特别是，我们研究剩余质量随额外维度大小的变化行为。 显示英文摘要

摘要： In order to improve simulations with domain wall fermions (DWFs), it has been suggested to project out a number of low-lying eigenvalues of the 4-dimensional Dirac operator that generates the transfer matrix of DWF. We investigate how this projection method affects chiral properties of quenched DWF. In particular, we study the behaviour of the residual mass as a function of the size of the extra dimension.
