摘要

基于扭曲质量价夸克的重夸克计划的第一阶段已经在去年的晶格会议上提出。CLS $N_f=2+1$系综被用于它们的精细晶格间距,而扭转质量有望进一步减少离散误差,并允许完全相对论性计算。我们给出了对应于$D\到K$和$D\到$ pi$的三个点函数的策略和初步结果。作为第一步获得的$m_u=m_d=m_s$夸克质量的形状因子在这里显示为在$q^2=0$时统计精度的百分比水平。

Heavy semileptonics with a fully relativistic mixed action
The first phase of a heavy quark program based on twisted mass valence quarks has been presented at last years's lattice conference. The CLS $N_f=2+1$ ensembles were used for their fine lattice spacing, while twisting the masses is expected to reduce discretisation errors even further and allow for a fully relativistic calculation. We present our strategy and preliminary results on three point functions, corresponding to $D\to K$ and $D\to\pi$ semileptonic decays. The form factors for $m_u=m_d=m_s$ quark masses obtained as a first step are shown here to be at the percent level in statistical precision at $q^2=0$.
