Measurement of the Radiative Decay Widths of the $$A^+_2$$ and $$K^{+^+}$$ (1430) Mesons
- Rochester U.
We have investigated for the first time the coherent productions of the $$A^+_2$$ and $$K^{+^+}$$ (l430) mesons in the nuclear Coulomb field of Pb and Cu. The experiment was performed at Fermi lab using a high resolution forward spectrometer consisting of proportional and drift chambers plus a liquid argon photon calorimeter. The incident momentum was 200 Gev/c. We found that at this momentum strong production mechanisms give very small contributions. The data were analyzed allowing for a small amount of hadronic background to interfere with the dominant electromagnetic production of the $$A^+_2$$ and $$K^{+^+}$$ (1430) mesons. The results were used to extract values for the radiative decay widths of these mesons
