Resonance formation in the π+ π− π0 final state in two-photon collisions
Abstract
A study of resonance formation is presented in the π+π−π0 final state in two-photon collisions at LEP. The a2(1320) radiative width is measured to be Λγγ = 0.98 ± 0.05 ± 0.09 keV. The helicity 2 production is dominant. Exclusive π+π−π0 production has also been studied in the mass region above the a2 in the ϱπ and f2π channels. This region is dominated by a JP = 2+ helicity 2 wave.
