Study off o (995) resonance in the ?0?0 decay channel

A high-statistics study of the π0π0-system produced in the π- p→π0π0 n reaction at 38GeV/c has been carried out at the IHEP accelerator using the GAMS-2000 multiphoton spectrometer. A partial-wave analysis which includesS, D 0, D− andD + waves has been performed in the |t|-range up to 1 (GeV/c)2. TheS */f 0(980) resonance is seen as a dip in theS-wave amplitude at small |t|. A distinct peak with a mass of 997±5MeV and a width of 48±10MeV is observed in theS-wave at |t|>0.3 (GeV/c)2. The production cross sections are measured.
