Radiative corrections in high energy Compton scattering
Radiative corrections (RC) to the differential and total Compton scattering cross sections are calculated. We consider the scattering of photon with a few GeV energy by the atomic electron.

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Radiative corrections (RC) to the differential and total Compton scattering cross sections are calculated. We consider the scattering of photon with a few GeV energy by the atomic electron. The reason is the unique possibility of precise measurement of respective cross sections in the PrimEx experiment (Jefferson Lab., CEBAF), where the high-precision value of π⁰ → 2γ width was measured, and where this process used in normalization goals. RC include the contributions from one-loop diagrams as well the effects due to additional real photon emission. The FORTRAN CODE for calculation of elastic and inelastic cross sections which takes into account different restrictions on event selection is created. Some underlying semi-analytical formulas are given. γ |
