Observation of the decay Λc+→Σ−π+π+π0

We report the first observation of the decay Λc+→Σ−π+π+π0, based on data obtained in e+e− annihilations with an integrated luminosity of 567 pb−1 at s=4.6 GeV. The data were collected with the BESIII detector at the BEPCII storage rings. The absolute branching fraction B(Λc+→Σ−π+π+π0) is determined...
