QED in strong fields

We discuss the status of atomic physics in strong field. We focus on the problem of electron-positron lines observed in heavy-ion collisions and on QED effects, calculated in strong Coulomb fields, especially Delbrück-scattering. We discuss the similarities and differences between these effects and channeling respectively beamstrahlung. We investigated the prospects for photon-channeling, calcu...

Universal Higher Order QED Corrections to Polarized Lepton Scattering

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 ...

Universal 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.
