On the RG flow of the Newton and cosmological constant

TL;DR

This paper defends previous work on the renormalization group flow of the Newton and cosmological constants, refuting recent claims that challenge its validity, and clarifies the robustness of the original results.

Contribution

It provides a critical rebuttal to recent criticisms, reaffirming the validity of earlier findings on the RG flow of fundamental constants in gravity.

Findings

Recent claims are flawed and unreliable

The original analysis of RG flow remains valid

The paper clarifies misunderstandings about the methodology

Abstract

In this note we comment on the RG flow of the Newton and cosmological constants, also in view of some recent claims [1] that would rise some doubts on the validity of our recent work [2,3]. Here we show that the arguments and claims of [1] are seriously flawed and cannot be trusted.
