Description

Within the quantum-field-theoretic Hamiltonian variational approach, we study the relativistic and meson-mass effects in the two-photon widths of pseudoscalar quarkonium. In this method, quarkonium resonances appear in the two-photon scattering cross section and thus the physical meson masses are automatically incorporated. Comparisons are made with other approaches and experimental data
