Compton scattering cross section differential cross section for Compton scattering in three-level QED
Author(s): Roqia Motammahid
Abstract: Scattering cross section may be defined in nuclear, atomic, and particle physics for collisions of accelerated beams of one type of particles with targets (either stationary or moving) of a second type of particles. The probability for any given reaction to occur is in proportion to its cross section. Thus, specifying the cross section for a given reaction is a proxy for stating the probability that a given scattering process will occur.in this paper. At first i have been considered differential cross section for Compton scattering with regard to lab frame and CM (center of mass) in QED the second, I analyze Compton Scattering cross section in QCD and QMC Theories.
The various cross sections of unpolarized Compton peppering is designed with respect to both t and

which is assessed to first instruction in

that are used in perturbative QED. By using two diverse methods in which two center of mass and lab frames are worked the Klein - Nishina formula is derived from. Plots of

which is decreased quickly to
