论文摘要
我们在$ n_f = 4 $ rgi方案中为Charm Quark质量提供了初步结果。这些是使用$ n_f = 2+1 $ cls合奏获得的,其中$ \ mathcal {o}(a)$非扰动改进的威尔逊·费米斯(Wilson Fermions)。我们采用了五个不同的晶格间距,范围为$ a \ lyssim 0.04 $ fm,并意识到了大约物理锥子和kaon群众,并在夸克质量平面的三个不同轨迹上分布了合奏,从而彻底研究了对晶格间距和光和奇怪的海夸克群体的依赖。我们勾勒出我们的分析策略,发现目前的主要错误是由于重新归一化和规模设定不确定性所致。
We present preliminary results for the charm quark mass in the $N_f=4$ RGI scheme. These were obtained using $N_f=2+1$ CLS ensembles with $\mathcal{O}(a)$ non-perturbatively improved Wilson fermions. We employed five different lattice spacings, ranging down to $a\lesssim 0.04$ fm and realized approximately physical pion and kaon masses, with ensembles spread out along three different trajectories in the quark mass plane, enabling a thorough study of the dependence on the lattice spacing and the light and strange sea quark masses. We sketch our analysis strategy and find that the dominant errors at present are due to the renormalization and scale setting uncertainties.
