The onset of spin rotation effects in electroproduction of heavy quarkonia

Original language description

We discuss the Melosh spin rotation effects in diffractive photo- and electroproduction of heavy quarkonia off a nucleon target in the dipole picture. The quarkonium light-front wave functions are obtained in the Schroedinger equation based formalism using the realistic interquark interaction potentials. A strong onset of spin rotation effects predicted in the case of J/psi(1S) photoproduction enables us to reach a reasonable agreement with the available data. In the case of radially excited 2S and 3S states these effects are even stronger as a direct manifestation of the nodal structure of their wave functions. In particular, the spin effects enhance the Psi '(2S) cross section by a factor of 2 - 3 and therefore cause a substantial increase of the Psi '(2S)-to-J/Psi(1S) ratio improving the description of experimental data.
