Abstract
In this article, we will look at some fundamental concepts in Particle Physics through the detailed study of a specific process of Quantum Electrodynamics (QED): the Bhabha scattering. It occurs in the interaction between an electron and its antiparticle, the positron, one of the basic QED processes. Our choice for work this process is due to the wealth of details provided by the two possibilities (channels) of interaction which serve to illustrate the calculation of interference between possibilities. Furthermore, this process is used to determine the luminosity of a particular collider, which ensures greater accuracy in measurements of other relevant quantities for the analysis of interactions between particles. Finally, comparing the QED prediction with the experimental results of the DESY-PETRA-TASSO experiment.
