The absolute branching fraction of D+ -> K-S(0)pi(+)pi(0)pi(0) is measured to be (2.888 +/- 0.058(stat.) +/- 0.069(syst.))%. The dominant intermediate processes are D+ -> K(S)(0)a(1)(1260)(+)(-> rho(+)pi(0)) and D+ -> K-*0 rho(+), with branching fractions of (8.66 +/- 1.04(stat.) +/- 1.39(syst.)) x 10(-3) and (9.70 +/- 0.81(stat.) +/- 0.53(syst.)) x 10(-3), respectively.eninfo:eu-repo/semantics/openAccessBranching FractionCharm PhysicsE(+)-E(-) ExperimentsParticle And Resonance ProductionArticle9WOS:0010847577000012-s2.0-85171352056N/A10.1007/JHEP09(2023)077Q2
