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…
Does the weak coupling limit of the Burden-Tjiang deconstruction of the massless quenched QED3 vertex agree with perturbation theory?
A. Bashir, A. Kizilersu, M. R. Pennington
We derive constraints on the non-perturbative 3-point fermion-boson transverse vertex in massless QED3 from its perturbative calculation to order . We also check the transversal…
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,…
