我们对手性对称费米子的五维公式进行了算法性能、手性对称破坏和拓扑隧道的比较研究，以寻找一个计算成本低廉且手性对称性好的公式。通过选择晶格作用，我们已经在精细晶格上进行了大规模的模拟，旨在精确研究轻夸克和重夸克物理。我们报告了比较研究、大尺度模拟的现状以及关于剩余夸克质量和自相关的初步结果。
We carry out a comparative study among five-dimensional formulations of chirally symmetric fermions about the algorithmic performance, chiral symmetry violation and topological tunneling to find a computationally inexpensive formulation with good chiral symmetry. With our choice of the lattice action, we have launched large-scale simulations on fine lattices aiming at a precision study of light and heavy quark physics. We report on the comparative study, current status of the large-scale simulations, and preliminary results on the residual quark mass and auto-correlation.
