摘要：

We have carried out the hyperon photo-production experiment at E-gamma = 1.5 - 2.4 GeV to study the properties of Lambda*(1405) hyperon through the lineshapes in terms of the pi(+)Sigma(-) and pi(-)Sigma(+) decay channels. To obtain clear event samples of Lambda*(1405), a Time Projection Chamber (TPC) has been constructed as a 4 pi detector. Since the mass of Lambda*(1405) lies close to the Sigma*(1385), the estimation of the Sigma*(1385) contamination to the Lambda*(1405) invariant mass spectrum is important. We report the status of analysis of the Lambda*(1405) lineshape with an emphasis on the study of the contamination from the nearby resonance Sigma*(1385).
