通过使用 BESIII 探测器分析在 3.773 GeV 质心能量处采集的积分光度 $2.93\,\rm fb^{-1}$ 的正电子碰撞数据样本，我们首次获得了 $D^0$ 和 $D^+$ 七个强子衰变模式的绝对分支分数，并搜索了强子衰变 $D^0\to K^0_S K^0_S\pi^0$ 灵敏度大大提高。结果为 ${\mathcal B}(D^0\to K^0_S\pi^0\pi^0\pi^0 )=( 7.64\pm 0.30\pm 0.29)\times 10^{-3}$, ${\mathcal B}(D^0\to K^-\pi^+\pi^0\pi^0\pi^0 )=( 9.54\pm 0.30\pm 0.31)\times 10^{-3}$, ${\mathcal B}(D^0\to K^0_S\pi^+\pi^-\pi^0\pi^0)=(12.66\pm 0.45\pm 0.43)\times 10^{-3}$, ${\mathcal B}(D^+\to K^0_S\pi^+\pi^0\pi^0 )=(29.04\pm 0.62\pm 0.87)\times 10^{-3}$, ${\mathcal B}(D^+\to K^0_S\pi^+\pi^+\pi^-\pi^0)=(15.28\pm 0.57\pm 0.60)\times 10^{-3}$, ${\mathcal B}(D^+\至 K^0_S\pi^+\pi^0\pi^0\pi^0)=( 5.54\pm 0.44\pm 0.32)\times 10^{-3}$, ${\mathcal B}(D^+\至 K^-\pi^+\pi^+\pi^0\pi^0 )=( 4.95\pm 0.26\pm 0.19)\times 10^{-3}$, ${\mathcal B}({D^0\to K^0_S K^0_S\pi^0})<1.57 \times 10^{-4}$ 在 90\% 置信度下。这里第一个不确定性是统计性的，第二个是系统性的。新研究的衰变极大地丰富了$D\to \bar K\pi\pi\pi$和$D\to \bar K\pi\pi\pi\pi$强子衰变的知识，并为访问更多包含粲扇区中标量、矢量、轴和张量介子的二体强子$D$衰变打开了桥梁。

By analyzing an electron-positron collision data sample corresponding to an integrated luminosity of $2.93\,\rm fb^{-1}$ taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we obtain for the first time the absolute branching fractions for seven $D^0$ and $D^+$ hadronic decay modes and search for the hadronic decay $D^0\to K^0_S K^0_S\pi^0$ with much improved sensitivity. The results are ${\mathcal B}(D^0\to K^0_S\pi^0\pi^0\pi^0 )=( 7.64\pm 0.30\pm 0.29)\times 10^{-3}$, ${\mathcal B}(D^0\to K^-\pi^+\pi^0\pi^0\pi^0 )=( 9.54\pm 0.30\pm 0.31)\times 10^{-3}$, ${\mathcal B}(D^0\to K^0_S\pi^+\pi^-\pi^0\pi^0)=(12.66\pm 0.45\pm 0.43)\times 10^{-3}$, ${\mathcal B}(D^+\to K^0_S\pi^+\pi^0\pi^0 )=(29.04\pm 0.62\pm 0.87)\times 10^{-3}$, ${\mathcal B}(D^+\to K^0_S\pi^+\pi^+\pi^-\pi^0)=(15.28\pm 0.57\pm 0.60)\times 10^{-3}$, ${\mathcal B}(D^+\to K^0_S\pi^+\pi^0\pi^0\pi^0)=( 5.54\pm 0.44\pm 0.32)\times 10^{-3}$, ${\mathcal B}(D^+\to K^-\pi^+\pi^+\pi^0\pi^0 )=( 4.95\pm 0.26\pm 0.19)\times 10^{-3}$, ${\mathcal B}({D^0\to K^0_S K^0_S\pi^0})<1.57 \times 10^{-4}$ at the 90\% confidence level. Here the first uncertainties are statistical and the second ones systematic. The newly studied decays greatly enrich the knowledge of the $D\to \bar K\pi\pi\pi$ and $D\to \bar K\pi\pi\pi\pi$ hadronic decays, and open a bridge to access more two-body hadronic $D$ decays containing scalar, vector, axial and tensor mesons in the charm sector.
