Functional matching and renormalization group equations at two-loop order

Physics Letters B
We present a systematic method for determining the two-loop effective Lagrangian resulting from integrating out a set of heavy particles in an ultraviolet scalar theory.

Isotropic Lifshitz point in the O(N) theory

Physics Letters B, 2017
The presence of an isotropic tricritical Lifshitz point for the O(N) scalar theory is investigated at large N in the improved Local Potential Approximation (LPA′) by means of the Functional Renormalization Group equations.

Asymptotically safe gravity with fermions

Physics Letters B, 2020
We use the functional renormalization group equation for the effective average action to study the fixed point structure of gravity-fermion systems on a curved background spacetime.

Exact expressions for the renormalization constants in the MS-like schemes [PDF]

arXiv
We briefly review how it is possible to derive some exact expressions for the renormalization constants for the MS-like renormalization prescriptions using the arguments based on the renormalization group. These expressions are obtained for a version of the dimensional technique in which the dimensionful parameter $\Lambda$ differs from the ...
