Study of the Lambda(1405) Resonance Through its Neutral and Charged Decay Channels by AMADEUS at DAPhiNE
The AMADEUS collaboration has the goal to perform unprecedented measurements in the field of the low-energy charged kaons-nuclei interactions, by implementing the existing KLOE detector with a dedicated setup in the inner region. The KLOE detector at DAΦNE represents a unique opportunity to perform a complete study of the Λ(1405) resonance through all its three Σπ decay channels. The importance of these measurements relies on the possibility to compare the different results for the various decay channels, investigating their contributions to the final resonance shape. In particular, one of the main differences between the neutral and charged Σπ channels is the presence of a second resonance, the Σ(1385), whose contribution to the final Λ(1405) spectra has to be evaluated and subtracted. Very promising preliminary results have been already obtained for the Σ^0π^0 decay channel to which, for isospin selection rules, the Σ(1385) resonance can not decay, and for the Σ^+π^− decay channel analysis, and will be presented in this work.
