论文摘要
我们计算了六个两夸克操作员对重型黑龙的非静态衰减宽度的贡献，这是由于风味变化的夸张夸克膨胀中的廉价夸克过渡变化。 Darwin Term $ρ_d$和Spin-Orbit项$ρ_ {\ rm LS} $的分析表达式以领先的订单准确度获得。
We compute the contributions of dimension six two-quark operators to the non-leptonic decay width of heavy hadrons due to the flavor changing bottom-to-up-quark transition in the heavy quark expansion. Analytical expressions for the Darwin term $ρ_D$ and the spin-orbit term $ρ_{\rm LS}$ are obtained with leading order accuracy.
