Gauge and parametrization dependencies of the one-loop counterterms in the Einstein gravity.

TL;DR

This paper investigates how gauge choices and parametrization affect the one-loop counterterms in Einstein gravity, exploring their physical significance and implications for renormalization group functions in nonrenormalizable theories.

Contribution

It provides a detailed analysis of the gauge and parametrization dependencies of one-loop counterterms in Einstein gravity and discusses their physical interpretation.

Findings

Counterterms depend on gauge and parametrization choices

Loop calculations have physical meaning on the mass shell

Renormalization group functions are parametrization-dependent in nonrenormalizable theories

Abstract

The parametrization and gauge dependencies of the one-loop counterterms on the mass-shell in the Einstein gravity are investigated. The physical meaning of the loop calculation results on the mass shell and the parametrization dependence of the renormgroup functions in the nonrenormalizable theories are discussed.
