Resumen

An amplitude analysis of the Cabibbo-favored decay D⁺ → K⁻π⁺π⁺π⁰ is performed, using 7.93 fb⁻¹ of e⁺e⁻ collision data collected with the BESIII detector at the center-of-mass energy of 3.773 GeV. The branching fractions of the intermediate processes are measured, with the dominant contribution D+→K¯∗8920ρ770+ observed to have a branching fraction of (4.35 ± 0.07_stat.± 0.17_syst.)%. With the detection efficiency derived from the amplitude analysis, the absolute branching fraction of D⁺→ K⁻π⁺π⁺π⁰ is measured to be (6.35 ± 0.04_stat.± 0.07_syst.)%.
