标题： Non-perturbative Renormalisation of Domain Wall Fermions: Quark Bilinears

摘要： 我们研究了哈希域墙费米子作用下夸克场和味非奇异费米子双线性算符的重正化系数，使用的是正则化无关（RI）重正化方案。 我们的结果来自淬火模拟，在一个16³×32的格点上，β=6.0，第五维的延展为16。 我们还讨论了有限第五维哈希域墙费米子模拟中固有的剩余手征对称破缺的预期效应，并研究了我们的数值结果中显式和自发手征对称破缺效应的证据。 我们发现，手征对称性所预测的不同重正化因子之间的关系在很大程度上被我们的结果所满足，并且由（低能）自发手征对称破缺和零模引起的系统效应是可以控制的。 我们将我们的结果与微扰论预测进行了比较，包括绝对值和重正化尺度依赖性。 显示英文摘要

摘要： We find the renormalisation coefficients of the quark field and the flavour non-singlet fermion bilinear operators for the domain wall fermion action, in the regularisation independent (RI) renormalisation scheme. Our results are from a quenched simulation, on a 16^3x32 lattice, with beta=6.0 and an extent in the fifth dimension of 16. We also discuss the expected effects of the residual chiral symmetry breaking inherent in a domain wall fermion simulation with a finite fifth dimension, and study the evidence for both explicit and spontaneous chiral symmetry breaking effects in our numerical results. We find that the relations between different renormalisation factors predicted by chiral symmetry are, to a good approximation, satisfied by our results and that systematic effects due to the (low energy) spontaneous chiral symmetry breaking and zero-modes can be controlled. Our results are compared against the perturbative predictions for both their absolute value and renormalisation scale dependence.
