Scalar QED as a toy model for higher-order effects in classical gravitational scattering
نویسندگان
چکیده
Quantum Electrodynamics (QED) serves as a useful toy model for classical observables in gravitational two-body systems with reduced complexity due to the linearity of QED. We investigate scattering scalar QED at sixth order charges (two-loop order) regime analogous post-Minkowskian expansion General Relativity. employ modern amplitude tools and extract by both eikonal methods formalism Kosower, Maybee, O'Connell (KMOC). In addition, we provide simplified approach extracting radial action beyond conservative sector.

We calculate the universal radiative QED corrections to polarized lepton scattering for general scattering cross sections in analytic form. The flavor non–singlet and singlet radiation functions are calculated to O((αL)5). The resummation of the non–singlet and singlet contributions to the QED–anomalous dimensions ∝ (α ln(x))k is performed to all orders. Numerical results are presented for the ...
متن کاملUniversal Higher Order Singlet QED Corrections to Unpolarized Lepton Scattering
We calculate the universal flavor-singlet radiative QED corrections to unpolarized lepton scattering applicable to general differential scattering cross sections, involving charged fermions or photons in initial or final states. The radiators are derived to O((α ln(Q/mf )) 5) in analytic form. Numerical illustrations are given.
