DOI: 10.1103/physrevd.96.056003
Abstract: We apply three forward light-by-light scattering sum rules to charmonium states. We show that these sum rules imply a cancellation between charmonium bound state contributions, which are mostly known from the $\gamma \gamma$ decay widths… read more here.

DOI: 10.1140/epjc/s10052-020-08444-3
Abstract: We perform a lattice QCD calculation of the hadronic light-by-light contribution to $$(g-2)_\mu $$ at the SU(3) flavor-symmetric point $$m_\pi =m_K\simeq 420\,$$ MeV. The representation used is based on coordinate-space perturbation theory, with all QED… read more here.

DOI: 10.3390/universe6110211
Abstract: Selection rules that follow from parity and four-momentum conservation are listed for head-on light-by-light scattering in a strong magnetic field taking into account nontrivial dispersion laws of different photon eigen-modes. The wave-length shifts occur for… read more here.
