Observation of a new Ω^*^- at 2.47 GeVc^2 in K^-p interactions at 11 GeVc

Clear evidence is presented for an Ω^*^- resonance of mass 2474+/-12 MeVc^2 and width 72+/-33 MeVc^2 in K^-p interactions at 11 GeVc. The state is observed in the Ω^-π^+π^- decay mode, and the corresponding inclusive cross section, corrected for Ω^-π^0π^0 decay, is estimated to be 290+/-90 nb....
