Renormalization scheme dependence and renormalization group summation [PDF]
We consider logarithmic contributions to the free energy, instanton effective action, and Laplace sum rules in QCD that are a consequence of radiative corrections. Upon summing these contributions by using the renormalization group, all dependence on the renormalization scale parameter μ cancels.

Automatic differentiable numerical renormalization group
Machine learning techniques have recently gained prominence in physics, yielding a host of new results and insights. One key concept is that of backpropagation, which computes the exact gradient of any output of a program with respect to any input.

On ambiguities and divergences in perturbative renormalization group functions [PDF]
There is an ambiguity in choosing field-strength renormalization factors in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme starting from the 3-loop order in perturbation theory.

Neural Monte Carlo renormalization group
The key idea behind the renormalization group (RG) transformation is that properties of physical systems with very different microscopic makeups can be characterized by a few universal parameters.

Ward-constrained melonic renormalization group flow
In recent years, interesting investigations of the nonperturbative renormalization group equations for tensorial group field theories have been performed in the truncation method, while completely discarding the Ward identities from their analysis.

Higher logarithms and ε-poles for the MS-like renormalization prescriptions
We consider a version of dimensional regularization (reduction) in which the dimensionful regularization parameter Λ is in general different from the renormalization scale μ.

New developments in the Renormalization Group [PDF]
In the first part of the thesis, we review the basics of the Exact Renormalization Group. In the central part, we design a specific choice of renormalization scheme in the context of Functional Renormalization Group to achieve the nonperturbative ...

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