Abstract

I(J P) = 1 2 ( ≥ 5 2?)Status: ∗∗∗ The evidence for this state has been much improved by HEMING-WAY 77, who see an eight standard deviation enhancement in Σ K and a weaker coupling to ΛK. ALITTI 68 and HEMINGWAY 77 observe no signals in the Ξ ππ (or Ξ(1530)π) channel, in contrast to DIBIANCA 75. The decay (Λ/Σ)K π reported by BARTSCH 69 is also not confirmed by HEMINGWAY 77. A moments analysis of the HEMINGWAY 77 data indicates at a level of three standard deviations that J ≥ 5/2. Ξ(2030) MASS VALUE (MeV) EVTS DOCUMENT ID TECN CHG COMMEN
