Abstract

Coherent π⁺π^-π^- production in the interactions of a beam of 600 GeV π^- mesons with C, Cu and Pb nuclei has been studied with the SELEX facility (Experiment E781 at Fermilab). The a₂(1320) meson signal has been detected in the Coulomb (low q²) region. The Primakoff formalism used to extract radiative decay width of this meson yields Γ = 284 ± 25 ± 25 keV, which is the most precise measurement to date.
