• Based on an 𝑒+⁢𝑒− collision data sample corresponding to an integrated luminosity of 2.93  fb−1 collected with the BESIII detector at √𝑠=3.773  GeV, the first amplitude analysis of the singly Cabibbo-suppressed decay 𝐷+→𝐾+⁢𝐾0𝑆⁢𝜋0 is performed. From the amplitude analysis, the 𝐾*⁢(892)+⁢𝐾0𝑆 component is found to be dominant with a fraction of (57.1±2.6±4.2)%, where the first uncertainty is statistical and the second systematic. In combination with the absolute branching fraction ℬ⁡(𝐷+→𝐾+⁢𝐾0𝑆⁢𝜋0) measured by BESIII, we obtain ℬ⁡(𝐷+→𝐾*⁢(892)+⁢𝐾0𝑆)=(8.69±0.40±0.64±0.51)×10−3, where the third uncertainty is due to the branching fraction ℬ⁡(𝐷+→𝐾+⁢𝐾0𝑆⁢𝜋0). The precision of this result is significantly improved compared to the previous measurement. This result also differs from most of theoretical predictions by about 4⁢𝜎, which may help to improve the understanding of the dynamics behind.
