MEASUREMENT OF THE RADIATIVE WIDTH OF THE A2(1320) IN 2-PHOTON INTERACTIONS

MEASUREMENT OF THE RADIATIVE WIDTH OF THE A2(1320) IN 2-PHOTON INTERACTIONS

The reaction e+e-→e+e- A2 (1320) has been observed by detecting the decay A2→π+,π-π0. The two-photon width of the A2 has been measured to be G{cyrillic}(A2→γγ)=(0.09±0.27 (stat)±0.16 (syst)) keV. The cross section σ(γγ→π+,π-π0 has been determined outside the A2 resonance region. © 1986 Springer-Verl...
