Abstract

A search for rare decay η′ → 4 π0 has been performed with GAMS-4π setup. The new upper limit is BR (η′ → 4 π0) < 3.2 ⋅10-4 at 90% confidence level. The π- p charge-exchange reaction at 32.5 GeV /c was used as a source of 1.3⋅106η′ mesons. Experiment was carried out at the IHEP U-70 accelerator.
