Interpolation Formulas for Asymptotically Safe Cosmology

open access: yesUniverse, 2023
Simple interpolation formulas are proposed for the description of the renormalization group (RG) scale dependences of the gravitational couplings in the framework of the 2-parameters Einstein-Hilbert (EH) theory of gravity and applied to a simple ...

Multi-collinear splitting kernels for track function evolution

open access: yesJournal of High Energy Physics, 2023
Jets and their substructure play a central role in many analyses at the Large Hadron Collider (LHC). To improve the precision of measurements, as well as to enable measurement of jet substructure at increasingly small angular scales, tracking information

Triad second renormalization group

open access: yesJournal of High Energy Physics, 2022
We propose a second renormalization group (SRG) in the triad representation of tensor networks. The SRG method improves two parts of the triad tensor renormalization group, which are the decomposition of intermediate tensors and the preparation of ...

Renormalization group evolution with scalar leptoquarks

open access: yesJournal of High Energy Physics, 2023
Leptoquarks are theoretically well-motivated and have received increasing attention in recent years as they can explain several hints for physics beyond the Standard Model.

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.

Automatic differentiable numerical renormalization group

open access: yesPhysical Review Research, 2022
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.

Renormalization group and universality [PDF]

open access: yesPhysical Review D, 1995
It is argued that universality is severely limited for models with multiple fixed points. As a demonstration the renormalization group equations are presented for the potential and the wave function renormalization constants in the $O(N)$ scalar field theory.

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.
