An alternative interpretation of Belle data on γ-γ -> η'-π^+-π^-

Belle data on gamma-gamma -> eta'-pi-pi are refitted using a broad J^{PC}=0^(-+) signal peaking in the mass range 2250-2300 MeV, but without \eta (1760). There is the possibility that this broad 0^(-+) signal may be identified with the 0^(-+) glueball predicted originally by Morningstar and Peardon. The X(1835) is confirmed to have a resonant phase variation.
