Coupled channel analysis in the K$\overline{K}$ threshold region
Results of an energy-dependent phase-shift analysis for pi pi scattering between 900 and 1120 MeV mass are presented using data of the reactions pi /sup +or-/p to pi /sup +or-/ pi /sup +/n and pi /sup -/p to K/sup +/K/sup -/n. The I=0 S-wave becomes highly inelastic at KK threshold and accounts for...

| description | Results of an energy-dependent phase-shift analysis for pi pi scattering between 900 and 1120 MeV mass are presented using data of the reactions pi /sup +or-/p to pi /sup +or-/ pi /sup +/n and pi /sup -/p to K/sup +/K/sup -/n. The I=0 S-wave becomes highly inelastic at KK threshold and accounts for the structure in the pi pi system. A zero effective range approximation for the S-wave leads to a pole of the S-matrix which is located on the second Riemann sheet at (1012+or-6)-i(16+or-5) MeV. (26 refs). |
