标题： Light Quark Simulations With FLIC Fermions

摘要： 强子质量在冻结格点QCD中被计算，以研究一种新型的厚链钩形费米子作用量的标度行为，其中仅费米子作用量的无关项使用APE平滑链接构建。 考虑对应于m_pi / m_rho比值为0.35的轻夸克质量，以评估钩形费米子作用量的特殊配置问题。 这种厚链无关钩形（FLIC）费米子作用量提供了优于平均场改进的标度，并且相较于非微扰改进具有优势，包括减少的特殊配置。 显示英文摘要

摘要： Hadron masses are calculated in quenched lattice QCD in order to probe the scaling behavior of a novel fat-link clover fermion action in which only the irrelevant operators of the fermion action are constructed using APE-smeared links. Light quark masses corresponding to an m_pi / m_rho ratio of 0.35 are considered to assess the exceptional configuration problem of clover-fermion actions. This Fat-Link Irrelevant Clover (FLIC) fermion action provides scaling which is superior to mean-field improvement and offers advantages over nonperturbative improvement, including reduced exceptional configurations.
