标题： Form factors for semileptonic B-decays with HISQ light quarks and clover b-quarks in Fermilab interpretation

摘要： 我们计算了$B\to \pi$、$B\to K$和$B_s\to K$振幅的矢量、标量和张量形式因子，这些对于描述带电流和中性电流情况下$B$介子的半轻子衰变率是必需的。我们使用高度改进的阶梯夸克（HISQ）作用量来描述海夸克和轻价夸克。底夸克在费米实验室解释下由 Clover 作用量描述。模拟是在$N_f = 2+1+1$MILC HISQ 系列上进行的，其近似格点间距从$0.15$fm 下降到$0.057$fm。我们展示了形式因子的盲预结果。 显示英文摘要

摘要： We compute the vector, scalar, and tensor form factors for the $B\to \pi$, $B\to K$, and $B_s\to K$ amplitudes, which are needed to describe semileptonic $B$-meson decay rates for both the charged and neutral current cases. We use the highly improved staggered quark (HISQ) action for the sea and light valence quarks. The bottom quark is described by the clover action in the Fermilab interpretation. Simulations are carried out on $N_f = 2+1+1$ MILC HISQ ensembles at approximate lattice spacings from $0.15$ fm down to $0.057$ fm. We present blinded preliminary results for the form factors.
