We present the coupled channel model of the scalar isovector resonance photoproduction including the πη, KK̅ and πη′ channels and calculate resulting mass distribution and the cross section in the πη channel. We show that the shape of this mass distribution, is strongly affected by the phase of background amplitude. We also discuss the effect of inclusion the πη′ channel on the overall isovector photoproduction process.
