利用Kaplan费米子的Shamir{close_quote}s变体给出了QCD中的晶格计算，该计算在无限额外维的极限下保持了晶格上的连续体SU(N){sub L}{乘以}SU(N){sub R}手性对称性。特别地，我们证明了与K{sub 0}-{bar K}{sub 0}混合相关的介子质量和四夸克矩阵元素在手性极限下具有预期的行为，即使在额外维度上有适度程度的晶格上，例如N{sub s}=10。{版权所有}{ital 1997} {ital美国物理学会}
We present lattice calculations in QCD using Shamir{close_quote}s variant of Kaplan fermions which retain the continuum SU(N){sub L}{times}SU(N){sub R} chiral symmetry on the lattice in the limit of an infinite extra dimension. In particular, we show that the pion mass and the four quark matrix element related to K{sub 0}-{bar K}{sub 0} mixing have the expected behavior in the chiral limit, even on lattices with modest extent in the extra dimension, e.g., N{sub s}=10. {copyright} {ital 1997} {ital The American Physical Society}
