Field-theory Two-point Functions via Negative Dimension Integration
(Korean Physical Soc, 2012-03-01)
One-loop two-point functions play an important role in quantum field theories, being one of the primary divergent Feynman graphs that calls for regularization and renormalization procedures. These well-known functions are ...

Invariância de Rótulo e Shifts no Momento de Integração de um Diagrama de Feynman: termos de Superfície como Violadores da Supersimetria
(Universidade Federal de Minas GeraisUFMG, 2019-03-29)
Implicit regularization (IR) is a method that in the momentum space allows for the calculation of Feynman diagrams in an independent manner. The idea behind the IR is to extract the ultraviolet behavior of the amplitude ...
Feynman integrals with tensorial structure in the negative dimensional integration scheme
(1999-12-01)
The negative-dimensional integration method (NDIM) is revealing itself as a very useful technique for computing massless and/or massive Feynman integrals, covariant and noncovanant alike. Up until now however, the illustrative ...

Aspectos dimensionais da massa do fóton na eletrodinâmica quântica
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2014-12-10)
The gauge invariance of Quantum Electrodynamics establishes a non massive character for the photon field. Nevertheless, corrections at one loop level for the self-energy of the photon can induce mass generation in some ...
Cálculos de integrais de Feynman em teorias de campos
(Universidade Estadual Paulista (Unesp), 2003-04)
Usando a técnica conhecida como método de integração em dimensão negativa (NDIM), calculamos as funções de 2 e 3-pontos em 1-loop e analisamos seus casos particulares de maior interesse físico. Generalizamos esta aplicação ...
