Abstract:

According to Dalitz and Tuan's phenomenological analysis of K^--p reactions the recently discovered π-Λ resonance may be interpreted as caused by the existence of a quasi-bound state of K-N which decays into π-Λ. Granting this interpretation and considering dispersion relations together with experimental information, it is conjectured that the K-Λ (K-Σ) parity relative to N is odd (even) and hence the Σ-Λ relative parity is odd. Arguments for our conjecture are given concerning branching ratios of the decay of the quasi-bound state and also of the hyperon production in the K^--p absorption near the threshold.
