论文摘要
我们在$ b _ {（s）} $和$ d _ {（s）} $ Mesons的晶格计算中介绍了晶格计算，使用Oktay-kronfeld（OK）魅力和底部价值夸克（Oktay-Kronfeld（OK）），其群众的群体是非驾驶的。计算是在MILC合作生成的6个HISQ合奏中完成的，并使用$ n_f = 2+1+1 $口味。我们还将HISQ动作用于轻视夸克。结果以比率为$ f_ {b_s}/f_b $和$ f_ {d_s}/f_d $的结果，反映$ su（3）$ sumemmetry breaking，并且独立于轴向电流的重量化常数。
We present recent progress in the lattice calculation of leptonic decay constants for $B_{(s)}$ and $D_{(s)}$ mesons using the Oktay-Kronfeld (OK) action for charm and bottom valence quarks, whose masses are tuned non-perturbatively. The calculations are done on 6 HISQ ensembles generated by the MILC collaboration with $N_f=2+1+1$ flavors. We also use the HISQ action for the light spectator quarks. Results are presented for the ratios $f_{B_s}/f_B$ and $f_{D_s}/f_D$, which reflect $SU(3)$ flavor symmetry breaking, and are independent of the renormalization constants of the axial currents.
