| Abstract: | The results of studying the mass spectrum of μ+μ?γγ systems produced in π?p collisions at 25 and 33 GeV/c presented. The wide-aperture magnetic spectrometer with a hodoscope γ-detector was used to identify muon pairs and photons. There is a clear peak in the mass spectrum which corresponds to the decay ω → π0μ+μ? previously not observed. The branching ratio for the decay is estimated to be 9 × 10?5 with a systematic error of 50%. |
