The data were collected with the BESIII detector at the BEPCII storage rings. The absolute branching fraction B(Lambda(+)(c) -> Sigma(-)pi(+)pi(+)pi(0)) is determined to be (2.11 +/- 0.33(stat.) +/- 0.14(syst.))%. In addition, an improved measurement of B(Lambda(+)(c) -> Sigma(-)pi(+)pi(+)pi(0)) is determined as (1.81 +/- 0.17(stat.) +/- 0.09(syst.))%.eninfo:eu-repo/semantics/openAccessBranching fractionCharmed baryonWeak decays; e(+)e(-) annihilationBESIIIObservation of the decay Lambda(+)(c) -> Sigma(-)pi(+)pi(+)pi(0)Article2-s2.0-8503263329010.1016/j.physletb.2017.06.065Q1Q1WOS:000411369700054
