Abstrak

We measured a set of π ± Σ ∓ , π 0 Σ 0 , and π − Σ 0 invariant mass spectra below and above the ¯ KN mass threshold in K − induced reactions on deuteron. We deduced the S -wave ¯ KN → π Σ and ¯ KN → ¯ KN scattering amplitudes in the isospin 0 channel in the framework of a ¯ KN and π Σ coupled channel. We ﬁnd that a resonance pole corresponding to Λ (1405) is located at 1417.7 + 6 . 0 − 7 . 4 (ﬁtting errors) + 1 . 1 − 1 . 0 (systematic errors) + [ − 26 . 1 + 6 . 0 − 7 . 9 (ﬁtting errors) + 1 . 7 − 2 . 0 (systematic errors)] i MeV / c 2 , closer to the ¯ KN mass threshold than the value determined by the Particle Data Group.
