ABSTRACT

It is shown that the virtual states and relative momentum of the constituents of the bound states are very important for the cross section of the process e+e-→J/ψ+ηc with the help of the Bethe-Salpeter wave function description of the bound states. The gauge invariance of the cross section is demonstrated. The numerical results can explain the experimental data.
