With the detection efficiency based on the amplitude analysis results, the absolute branching fraction is measured to be B(D-s(+) -> K-S(0) pi(+) pi(0)) = (5.43 +/- 0.30(stat) +/- 0.15(syst)) x 10(-3).eninfo:eu-repo/semantics/openAccessBranching FractionCharm PhysicsE(+)-E(-) ExperimentsDecayArticle2-s2.0-8510916541910.1007/JHEP06(2021)1816Q2Q1WOS:000668895000001
