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…
Constraint on the QED Vertex from the Mass Anomalous Dimension
A. Bashir, M. R. Pennington
We discuss the structure of the non-perturbative fermion-boson vertex in quenched QED. We show that it is possible to construct a vertex which not only ensures that the fermion pro…
Gauge independent Chiral Symmetry Breaking in Quenched QED
A. Bashir, M. R. Pennington
In quenched QED we construct a non-perturbative fermion-boson vertex that ensures the fermion propagator satisfies the Ward-Takahashi identity, is multiplicatively renormalizable,…
