Abstract
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 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.
