Abstract：
A new particle Σ* with J^P=1/2^－ was predicted by unquenched quark models with its mass around the well established Σ(1385) with J^P=3/2⁺. Here we re-examine some old data of the K^－p→Λπ⁺π^－ reaction. Firstly we re-fit the data for kaon beam momenta in the range of 1.0－1.8 GeV. Secondly we study the reaction at the energies around Λ^*(1520) peak. Both studies show evidence for the existence of Σ^* with J^P=1/2－ around 1380 MeV. Higher statistic data on relevant reactions are needed to clarify the situation.
