The Covariant Approach for the Radiative Decay of the J/Ψ Meson and Relation to Amplitudes Extracted in the Helicity Basis

Abstract: We have developed the covariant approach for the partial wave analysis of the radiative decay of the vector meson into two pseudoscalar mesons based on the orbital momentum- intrinsic spin decomposition. This allowed us to include the data on the radiative J/{\Psi} decay into a large data base for analysis of the meson production reactions. The correspondence between partial wave amplitudes extracted in our approach and those extracted in the helicity basis is determined.
