Abstract

A measurement has been made of the relative signs of the resonant

K^{-} p \to Σ π

reaction amplitudes coming from partial waves corresponding to

Σ (1385)

,

Λ (1405)

, and

Λ (1520)

. From this it is shown that

Λ (1405)

and

Λ (1520)

are to be described as predominantly SU(3) singlets.
