Abstract

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 operating at the BEPCII collider, the branching fractions of three hadronic charm meson decays, D⁺→ ϕπ⁺π⁺π^-, D⁺→ K⁰_SK⁺π⁺π^-π⁰, and D⁺→ K⁰_SK⁺ω, are measured for the first time to be (0.54±0.19±0.02)× 10^-4, (2.51±0.34±0.14)× 10^-4, and (2.02±0.35±0.10)× 10^-4, respectively. Futhermore, the branching fractions of D⁺→ K⁺K^-π⁺π⁺π^- and D⁺→ K⁰_SK⁺η are measured with improved precision, yielding values of (0.66±0.11±0.03)× 10^-4 and (2.27±0.22±0.05)× 10^-4, respectively.
