Improved radiative corrections for (e,e'p) experiments - A novel approach to multi-photon bremsstrahlung

Understand

Radiative processes lead to important corrections to (e,e'p) experiments.

• While radiative corrections can be calculated exactly in QED and to a good accuracy also including hadronic corrections, these corrections cannot be included into data analyses to arbitrary orders exactly.
• Nevertheless consideration of multi-photon bremsstrahlung above the low-energy cut-off is important for many (e,e'p) experiments.
• To date, higher-order bremsstrahlung effects concerning electron scattering experiments have been implemented approximately by employing the soft-photon approximation (SPA).
