Abstract

The Λ(1405) production in p + p collisions at 3.5 GeV and K⁻-induced reactions is discussed. The shift of the measured spectral function of the Λ(1405) in p + p reactions does not match either theoretical calculations for p + p reactions or experimental observation in previous K⁻-induced reactions. New experiments with stopped and in-flight K⁻ are needed to study this initial state more in detail. The state of the art of the analysis is discussed.
