A triangle singularity in Lambda_c+ -> Lambda pi+ pi+ pi- enhances the dynamically generated Sigma*(1430), yielding a 1434 MeV pi+Lambda peak and a predicted 1875 MeV pi-Sigma* bump with branching fraction 3.5e-4.
(28) Next we give the step to evaluate the mass distribution with t o the explicit decay of Σ ∗(1430) toπ+Λ
