One-loop off-shell quark-gluon vertex in arbitrary gauge and dimensions: a streamlined approach through the second-order formalism of QCD
Victor Miguel Banda Guzmán, Adnan Bashir
The standard Feynman rules used for perturbative calculations in quantum chromodynamics (QCD) are derived from a Lagrangian that is first-order in derivatives. It includes a three-…

One loop reduced QED for massive fermions within an innovative formalism
Victor Miguel Banda Guzmán, Adnan Bashir, Luis Albino +1
We carry out a detailed study of the three-point fermion-photon interaction vertex at one loop order for massive fermions in reduced quantum electrodynamics. This calculation is ca…
