Studies of the Lambda(1405) in Proton-Proton Collisions with ANKE at COSY-Juelich
Abstract
Description
The lineshape of the Lambda(1405) was studied in the pp -> pK+ Y0 reaction at a beam momentum of 3.65 GeV/c at COSY-Juelich. The ANKE spectrometer was used to identify two protons, one positively charged kaon, and one negatively charged pion in the final state. Invariant-mass and missing-mass techniques were applied to separate two neighbouring neutral excited hyperon resonances, the Sigma0(1385) and Lambda(1405). Both the shape and the position of the Lambda(1405) distribution are similar to those measured in other reactions and this information contributes to the ongoing debate regarding the structure of this resonance.
