我们使用非微扰 $O(a)$ 改进的威尔逊费米子计算淬火晶格 QCD 中的强子质谱、夸克质量和介子衰变常数。对耦合常数 $\ensuremath{\beta}=6.0$ 和 6.2 的两个值进行计算，并将结果与普通威尔逊费米子的预测进行比较。我们发现改进后的动作减少了预期的晶格伪影。
We compute the hadron mass spectrum, the quark masses, and the meson decay constants in quenched lattice QCD with nonperturbatively $O(a)$-improved Wilson fermions. The calculations are done for two values of the coupling constant $\ensuremath{\beta}=6.0$ and 6.2, and the results are compared with the predictions of ordinary Wilson fermions. We find that the improved action reduces lattice artifacts as expected.
