Amplitude analysis and branching fraction measurement of the decay D-s(+) -> pi(+)pi(0)pi(0). JOURNAL OF HIGH ENERGY PHYSICS. (1).1029-8479https://doi.org/10.1007/JHEP01(2022)052https://hdl.handle.net/20.500.12713/2425Using a data set corresponding to an integrated luminosity of 6.32fb(-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(+) -> pi(+)pi(0)pi(0 ) is performed, and the relative fractions and phases of different intermediate processes are determined. The absolute branching fraction of the decay D-s(+) -> pi(+)pi(0)pi(0)is measured to be (0.50 +/- 0.04(stat) 0.02(syst) )%. The absolute branching fraction of the intermediate process D-s(+) -> f(0)(980)pi(+), f(0)(980) ->pi(0)pi(0 ), is determined to be (0.28 +/- 0.04(stat) +/- 0.04(syst))%.eninfo:eu-repo/semantics/openAccessBranching FractionCharm Physicse(+)-e(-) ExperimentsArticle1WOS:0007423615000012-s2.0-85123242495Q110.1007/JHEP01(2022)052Q2
