Suzuki, Alfredo Takashi [UNESP]2014-05-202014-05-202012-03-01Journal of The Korean Physical Society. Seoul: Korean Physical Soc, v. 60, n. 5, p. 704-713, 2012.0374-4884http://hdl.handle.net/11449/41968One-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 here revisited as illustrative for the power and the simplicity of the negative dimensional integration method (NDIM) approach to tackle Feynman integrals with off-shell external fields and massless and massive virtual fields.704-713engTwo-point functionsFeynman integralsNegative dimensionsField-theory Two-point Functions via Negative Dimension IntegrationArtigo10.3938/jkps.60.704WOS:000304099600007Acesso restrito7511139477883318
