Minkowski Space Dynamics and Light-Front Projection
Wayne de Paula, Tobias Frederico
We explore the connection between the four-dimensional Minkowski-space Bethe-Salpeter equation and its light-front projection, emphasizing the implications for bound-state dynamics…

On the momentum space structure of the quark propagator
O. Oliveira, T. Frederico, W. de Paula
The structure of the quark propagator in momentum space is explored taking into account non-perturbative QCD dynamics constraints for the quark spectral densities derived previousl…

On the conformal limit of a QED-inspired model
O Oliveira, T Frederico, W de Paula
A conformal invariant QED-inspired model is solved for a general covariant linear gauge using the Dyson-Schwinger equations for the propagators assuming a pure vector like interact…
