Espalhamento Compton na eletrodinâmica quântica com quebra de simetria de Lorentz

Abstract

After a review of Quantum Electrodynamics and the calculation in detail of the cross section associated with the Compton scattering effect, in this dissertation, we present the calculations of the Compton scattering cross section in a Quantum Electrodynamics model with a term that breaks Lorentz symmetry. In the model under study, we consider a Lorentz symmetry violation term that modifies the vertex of the theory leaving the propagators unchanged.
