Abstract
A bstract Using 20.3 fb − 1 of e + 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 D + → K + π 0 , D + → K + η and D + → K + η′ with the double-tag method, with significantly improved precision compared to the previous measurements. The statistical significance of each signal decay exceeds 10 σ . The branching fractions are determined to be ℬ( D + → K + π 0 ) = (1.45 ± 0.06 ± 0.08) × 10 − 4 , ℬ( D + → K + η ) = (1.17 ± 0.10 ± 0.03) × 10 − 4 and ℬ( D + → K + η′ ) = (1.88 ± 0.15 ± 0.11) × 10 − 4 , where the first uncertainties are statistical and the second systematic. The branching fractions of D + → K + η and D + → K + η′ are consistent with the world average values. The reported branching fraction of D + → K + π 0 deviates with the world average value by 3 σ .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
