Radiative Width of the a2 Meson

High Energy Physics - Experiment 2007-05-23 v3

Abstract

We present data on coherent production of the pi-pi-pi+ system by 600 GeV pion beam for the C, Cu and Pb targets. The Primakoff formalism was used for extracting the radiatve width of the a2 meson. We obtain a preliminary value \Gamma(a2->pi+gamma)=225+/-25(stat)+/-45(syst) keV.
