标题： $B\rightarrow D^{(*)}$ decays from $N_f=2+1+1$ highly improved staggered quarks and clover $b$-quark in the Fermilab interpretation

摘要： 我们对非零反冲下的半轻子 $B\rightarrow D^{(*)}$ 衰变分析进行了更新。 我们的计算使用了 $2 + 1 + 1$ FNAL-MILC 系综，其中海夸克和轻价夸克采用高度改进的阶梯式夸克（HISQ）作用量，而底夸克则采用费米实验室解释下的钩形作用量。 模拟在多个格点间距上进行，大约从 $\sim 0.15$ fm 到 $\sim 0.06$ fm，并且涉及各种夸克质量。 我们将概述该分析，并展示一些形式因子的初步结果。 显示英文摘要

摘要： We present an update on the analysis of semileptonic $B\rightarrow D^{(*)}$ decays at non-zero recoil. Our computation employs $2 + 1 + 1$ FNAL-MILC ensembles with highly improved staggered quark (HISQ) action for sea and light valence quarks, while the bottom quark is treated using the clover action in the Fermilab interpretation. Simulations are performed across several lattice spacings, ranging approximately from $\sim 0.15$ fm to $\sim 0.06$ fm, and for various quark masses. We will present an overview of the analysis and show some preliminary results for the form factors.
