英文摘要	A new particle Sigma* with J(P) = 1/2(-) was predicted by unquenched quark models with its mass around the well established Sigma(1385) with J(P) = 3/2(+) Here we re-examine some old data of the K(-)p --> Lambda pi(-)pi(+) 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 Lambda(1520) peak Both studies show evidence for the existence of Sigma* with J(P) = 1/2(-) around 1380 MeV Higher statistic data on relevant: reactions are needed to clarify the situation
