Using a data set corresponding to an integrated luminosity of 6.32 fb−1 recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, an amplitude analysis of the decay $$ {D}_s^{+} $$ D s + → π+π0π0 is performed, and the relative fractions and phases of different intermediate processes are determined. The absolute branching fraction of the decay $$ {D}_s^{+} $$ D s + → π+π0π0 is measured to be (0.50 ± 0.04stat ± 0.02syst)%. The absolute branching fraction of the intermediate process $$ {D}_s^{+} $$ D s + → f0(980)π+, f0(980) → π0π0 is determined to be (0.28 ± 0.04stat ± 0.04syst)%.

The Born cross sections of the processes e+e− → ωπ0 and e+e− → ωη are measured at center-of-mass energies between 3.773 and 4.701 GeV using a total integrated luminosity of 22.7 fb−1 collected with the BESIII detector operating at the BEPCII collider. A simple s−n dependence for the continuum process can describe the measured Born cross sections. No significant contributions from the ψ(4160), Y(4230), Y(4360), ψ(4415), Y(4660) resonances are found, which indicates relative small branching fractions for these resonances into the ωπ0 and ωη final states.

Using data collected with the BESIII detector in e + e − collisions at center-ofmass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb −1 of integrated luminosity, we report the amplitude analysis and branching-fraction measurement of the D + s → π + π 0 η decay. We find that the dominant intermediate process is D + s → ρ + η and the significances of other resonant and nonresonant processes are all less than 3σ. The upper limits on the branching fractions of S-wave and P -wave nonresonant components are set to 0.10% and 0.74% at the 90% confidence level, respectively. In addition, the branching fraction of the D + s → π + π 0 η decay is measured to be (6.15 ± 0.25(stat.) ± 0.18(syst.))%, which receives significant contribution only from D + s → ρ + η according to the amplitude analysis.
