论文摘要
通过在重夸克部门引入敷料功能的不同风味依赖性，修改了伯特盐盐方程的梯子内核。与较早的工作相比，这允许同时计算光谱和轻质衰减常数，$ d_U $，$ d_U $，$ d_s $，$ b_u $，$ b_u $，$ b_s $和$ b_c $ emesons和$ b_c $ emesons和heavy quarkonia $ quarkonia $ $η_c$和$η_c$和$η__b$ arne and and and and and and and and and pons fromall fromeral fromell fromeral pion pion。相应的伯特盐振幅振幅被投影到光线前，我们在整个理论中重建了介子的分布幅度。在重夸克有效理论中，与重膜分布幅度的第一反力矩进行了比较。
The ladder kernel of the Bethe-Salpeter equation is amended by introducing a different flavor dependence of the dressing functions in the heavy-quark sector. Compared with earlier work this allows for the simultaneous calculation of the mass spectrum and leptonic decay constants of light pseudoscalar mesons, the $D_u$, $D_s$, $B_u$, $B_s$ and $B_c$ mesons and the heavy quarkonia $η_c$ and $η_b$ within the same framework at a physical pion mass. The corresponding Bethe-Salpeter amplitudes are projected onto the light front and we reconstruct the distribution amplitudes of the mesons in the full theory. A comparison with the first inverse moment of the heavy meson distribution amplitude in heavy quark effective theory is made.
