Gauge (in)dependence and background field formalism

Physics Letters B, 2019
It is shown that the gauge invariance and gauge dependence properties of effective action for Yang-Mills theories should be considered as two independent issues in the background field formalism.

Functional renormalization group for fermions on a one dimensional lattice at arbitrary filling

SciPost Physics
A formalism based on the fermionic functional-renormalization-group approach to interacting electron models defined on a lattice is presented. One-loop flow equations for the coupling constants and susceptibilities in the particle-particle and particle ...

Higher $\varepsilon$-poles and logarithms in the MS-like schemes from the algebraic structure of the renormalization group [PDF]

arXiv
We investigate the structure of renormalization constants within the MS-like renormalization prescriptions for a version of dimensional regularization in which the dimensionful regularization parameter $\Lambda$ differs from the renormalization point $\mu$.
