$\Lambda (1405)$ observations in p+p and K${}^{-}$-induced reactions

Abstract

The $\Lambda (1405)$ production in p+p collisions at 3.5 GeV and K${}^{-}$-induced reactions is discussed. The shift of the measured spectral function of the $\Lambda (1405)$ 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.
