Study of D_s^+→f_0 (980) ρ^+ and ϕπ^+ decays through D_s^+→π^+ π^+ π^- π^0
The BESIII collaboration recently reported the first amplitude analysis and branching fraction measurement of D_s^+→π^+ π^+ π^- π^0 decays. The results have been published recently in Physics Review Letters on 7th Jan. 2025 [Phys. Rev. Lett. 134, 011904 (2025)].
