Search for the decay Y(1S) → γη′

Search for the decay Y(1S) → γη′

A study was carried out to search for the decay Υ → γη' with the decay mode η' → ηπ+π- and three decay modes of the η. Using simple, loose selection criteria, no candidates were found and the 90%C C.L. limit of B(Υ → γη') 1.6 × 10-5 was set.
