Description
A search for exotic I = 2 hyperons decaying into Σ-π- or Σ-π-π0 has been completed in the final states Σ+π-π- and Σπ-π-π0 produced in K-n interactions at 2.87 GeV/c. Cross sections for these two final states are 303 +- 31 μb and 660 +- 66 μb, respectively. Upper limits for exotic processes are sigma (K-n → Y*π+, Y* → Σ-π-) < 13 μb and sigma (K-n → Y*π+, Y* → Σ-π-π0) < 23 μb for GAMMA (Y*) < 120 MeV; sigma (K-n → Y*π+π0, Y* → Σ-π-) < 28 μb for GAMMA (Y*) < 80 MeV. Production cross sections have also been measured for all nonexotic resonances observed in the two final states
