Observation of a Ξ(2370) produced in 8.25 GeV/c K−p interactions

We observe production of a Ξ*(2370) in the reactions K−p→[YK¯π]K, [YK¯π]Kπ and [ΩK] (K or Kπ) at 8.25 GeV/c in a high statistics bubble chamber experiment. The mass and width are determined to be 2373 ± 8 MeV and 80 ± 25 MeV, respectively. The I = 1/2 assignment is strongly favoured.
