摘要：
本文报道D_s介子n_f=2+1组态半轻子衰变到η和η '的形状因子的晶格结果。计算包含断开费米子回路图，这是具有挑战性的计算上的晶格。我们的结果表明，断开图的形状因子的显着贡献。
英文摘要：
We report on lattice results of the form factors for semi-leptonic decays of the D_s meson to eta and eta', with n_f=2+1 configurations. The calculation contains disconnected fermion loop diagrams, which are challenging to calculate on the lattice. Our result shows that the disconnected diagrams give significant contributions to the form factors.
