Abstract

A search for the decays γ→ρπ, γ→J/ψX and γ→γa (where X is undetermined and a is an axion) has been completed using the LENA detector at the DORIS storage ring. No evidence for any of these processes was found. For these decay modes we set branching fraction upper limits (90% C.L.) of 2.1×10^-3, 2.0×10^-2 and 9.1×10^-4, respectively.
