论文摘要
我们使用具有最大扭曲的价费里在Cls $ n_f = 2+1 $ emembles上具有最大扭曲的价值费用的混合行动设置，以报告魅力物理学的第一组结果。该设置避免了需要改进系数减去$ O（AM_C）$效果。符号夸克质量，$ d $和$ d_s $衰减常数是在CLS合奏子集中计算的，该集合可以遵循连续限制并推断到物理旋转质量，并评估缩放属性。特别注意实施技术不确定性的技术。我们的结果显示了整个合奏中高精度计算的出色前景。
We report on our first set of results for charm physics, using a mixed-action setup with maximally twisted valence fermions on CLS $N_f=2+1$ ensembles. This setup avoids the need of improvement coefficients to subtract $O(am_c)$ effects. The charm quark mass, $D$ and $D_s$ decay constants are computed on a subset of CLS ensembles, which allows to take the continuum limit and extrapolate to the physical pion mass, and assess the scaling properties. Special attention is paid to the implementation of techniques to deal with systematic uncertainties. Our results show excellent prospects for high-precision computations on the full set of ensembles.
