Measurements of the absolute branching fractions of the doubly Cabibbo-suppressed decays $\textit{D}$

Using 20.3 fb of $\textit{e}$ $\textit{e}$ collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we present the measurements of the absolute branching fractions of the doubly Cabibbo-suppressed decays $\textit{D}$ → $\textit{K}$ $\textit{π}$ , $\textit{D}$ → $\textit{K}$ $\textit{η}$ and $\textit{D}$ → $\textit{K}$ $\textit{η′}$ with the double-tag method, with significantly improved precision compared to the previous measurements. The statistical significance of each signal decay exceeds 10$\textit{σ}$. The branching fractions are determined to be ℬ($\textit{D}$ → $\textit{K}$ $\textit{π}$ ) = (1.45 ± 0.06 ± 0.08) × 10 , ℬ($\textit{D}$ → $\textit{K}$ $\textit{η}$) = (1.17 ± 0.10 ± 0.03) × 10 and ℬ($\textit{D}$ → $\textit{K}$ $\textit{η′}$) = (1.88 ± 0.15 ± 0.11) × 10 , where the first uncertainties are statistical and the second systematic. The branching fractions of $\textit{D}$ $\textit{→ K}$ $\textit{η}$ and $\textit{D}$ $\textit{→ K}$ $\textit{η′}$ are consistent with the world average values. The reported branching fraction of $\textit{D}$ $\textit{→ K}$ $\textit{π}$ deviates with the world average value by 3$\textit{σ}$.
