Abstract

A search for the decay Ds+→η′π+;η′ →ρ{variant}γ has been performed by the NA14/2 photoproduction experiment at CERN. A signal compatible with the Ds+ has been observed, leading to a ratio of branching fractions of Br(Ds+→η′π+) Br(Ds+→φπ+)=2.5±1.0-0 .4+1.5. A value of Br(D+→η′π+) Br(D+→K-π+π+)< 0.1 is set at 90% CL. © 1991.
