摘要：

Using the CLAS detector system in Hall B at Jefferson Lab, we have done a high statistics measurement of the photoproduction of K(+)Lambda(1405) using a proton target. The reconstructed invariant mass seen in the various Sigma pi decay modes has been measured, as well as the differential cross section d sigma/dt. The nature of the Lambda(1405) with its peculiar mass distribution is not well understood, and studies have shown that it may posess strong dynamical components, which could be extracted from our data. Various aspects of our analysis are discussed, as well as future prospects to further enhance the precision of the results.
