On the equivalence between implicit regularization and constrained differential renormalization. [PDF]

open access: yes, 2008
Constrained differential renormalization (CDR) and the constrained version of implicit regularization are two regularization independent techniques that do not rely on dimensional continuation of the space-time.

General scalar renormalisation group equations at three-loop order

open access: yesJournal of High Energy Physics, 2020
For arbitrary scalar QFTs in four dimensions, renormalisation group equations of quartic and cubic interactions, mass terms, as well as field anomalous dimensions are computed at three-loop order in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme. Utilising

The renormalization group equations revisited [PDF]

open access: yes, 2018
International audienceStarting from a well-defined local Lagrangian, we analyze the renormalization group equations in terms of the two different arbitrary scales associated with the regularization procedure and with the physical renormalization of the ...

Regularization, renormalization and consistency conditions in QED with [PDF]

open access: yes, 2020
The present article is an important addition to the nonperturbative formulation of QED with x-steps presented by Gavrilov and Gitman (Phys. Rev. D. 93:045002, 2016).

On a realization of {β}-expansion in QCD

open access: yesJournal of High Energy Physics, 2017
We suggest a simple algebraic approach to fix the elements of the {β}-expansion for renormalization group invariant quantities, which uses additional degrees of freedom.

Off-shell divergences in quantum gravity

open access: yesJournal of High Energy Physics, 2023
We investigate off-shell perturbative renormalisation of pure quantum gravity for both background metric and quantum fluctuations. We show that at each new loop order, the divergences that do not vanish on-shell are constructed from only the total metric,

Renormalized measure of regular languages [PDF]

open access: yesInternational Journal of Control, 2006
This paper modifies the signed real measure of regular languages, which has been reported in recent literature for analysis and synthesis of discrete event supervisory control laws. A new concept of renormalized measure is introduced to eliminate a user-selectable parameter in the present version of the language ...

Localization of Gauge Theories on the Three-Sphere [PDF]

open access: yes, 2012
We describe the application of localization techniques to the path integral for supersymmetric gauge theories in three dimensions. The localization procedure reduces the computation of the expectation value of BPS observables to a calculation in a matrix

The Quadrupole Moment of Compact Binaries to the Fourth post-Newtonian Order: II. Dimensional Regularization and Renormalization [PDF]

open access: yes, 2022
The regularization and renormalization of the radiative mass-type quadrupole moment of inspiralling compact binaries (without spins) is investigated at the fourth post-Newtonian (4PN) approximation of general relativity.
