论文摘要
我们在2+1-Fravor lattice QCD中分析了包含的半蛋白质$ b \ x_c \ellν$结构功能。 Möbius域壁式羊式动作用于轻,奇怪,魅力和底部夸克。结构函数从各种独家模式中获得贡献,包括主要的s波状态$ d^{(*)} _ s $以及p-wave状态$ d_s^{**} $。我们可以在晶格数据中识别它们,从中我们对$ b_s \ to d_s^{**} \ellν$ form formals构成了一些约束。
We analyze the inclusive semileptonic $B \to X_c \ellν$ structure functions in 2+1-flavor lattice QCD. The Möbius domain-wall fermion action is used for light, strange, charm and bottom quarks. The structure function receives contributions from various exclusive modes, including the dominant S-wave states $D^{(*)}_s$ as well as the P-wave states $D_s^{**}$. We can identify them in the lattice data, from which we put some constraints on the $B_s \to D_s^{**}\ellν$ form factors.
