摘要

The nature of the Λ(1405), and its place in the baryon spectrum has remained uncertain for decades. Theoretical studies have shown that it may possess strong dynamical components which are not seen in other well-known baryons. Using the CLAS detector system in Hall B at Jefferson Lab, we have measured the photoproduction reaction γ + p → K~+Λ(1405) with high statistics and over different Σπ decay channels. The reconstructed invariant mass distribution (lineshape) has been measured, as well as the differential cross sections for the Λ(1405), Σ(1385), and Λ(1520). Our analysis method is discussed and our near-final results for the Λ(1405) lineshape and differential cross section are presented.
