Regularization and renormalization of gauge fields [PDF]

open access: yesNuclear Physics B, 1972
A new regularization and renormalization procedure is presented. It is particularly well suited for the treatment of gauge theories. The method works for theories that were known to be renormalizable as well as for Yang-Mills type theories. Overlapping divergencies are disentangled.

Self-renormalization of quasi-light-front correlators on the lattice [PDF]

open access: yesNuclear Physics B, 2021
In applying large-momentum effective theory, renormalization of the Euclidean correlators in lattice regularization is a challenge due to linear divergences in the self-energy of Wilson lines.

Universality in the Exact Renormalization Group: Comparison to Perturbation Theory

open access: yesUniverse, 2023
Various formulations of the exact renormalization group can be compared in the perturbative domain, in which we have reliable expressions for regularization-independent (universal) quantities.

Dimensional regularization vs methods in fixed dimension with and without γ 5

open access: yesJournal of High Energy Physics, 2018
We study the Lorentz and Dirac algebra, including the antisymmetric ϵ tensor and the γ 5 matrix, in implicit gauge-invariant regularization/renormalization methods defined in fixed integer dimensions.

Implicit Regularization and Renormalization of QCD [PDF]

open access: yesInternational Journal of Theoretical Physics, 2006
We apply the Implicit Regularization Technique (IR) in a non-abelian gauge theory. We show that IR preserves gauge symmetry as encoded in relations between the renormalizations constants required by the Slavnov-Taylor identities at the one loop level of QCD.

Manifestly N=2 supersymmetric regularization for N=2 supersymmetric field theories

open access: yesPhysics Letters B, 2015
We formulate the higher covariant derivative regularization for N=2 supersymmetric gauge theories in N=2 harmonic superspace. This regularization is constructed by adding the N=2 supersymmetric higher derivative term to the classical action and inserting

Renormalization of the pseudoscalar operator at four loops in QCD

open access: yesJournal of High Energy Physics
We present the renormalization constant of the pseudoscalar operator defined with a non-anticommuting γ 5 in dimensional regularization up to four-loop order in perturbative Quantum Chromodynamics (QCD).

Higher logarithms and ε-poles for the MS-like renormalization prescriptions

open access: yesJournal of High Energy Physics, 2023
We consider a version of dimensional regularization (reduction) in which the dimensionful regularization parameter Λ is in general different from the renormalization scale μ.

Leading all-loop quantum contribution to the effective potential in general scalar field theory

open access: yesJournal of High Energy Physics, 2023
The RG equation for the effective potential in the leading log (LL) approximation is constructed which is valid for an arbitrary scalar field theory in 4 dimensions.
