One-loop -point correlators in pure gravity

arXiv:2411.07939 · doi:10.1103/PhysRevLett.134.111602

Abstract

In this work we propose a simple algebraic recursion for the complete one-loop integrands of -graviton correlators. This formula automatically yields the correct symmetry factors of individual diagrams, taking into account both the graviton and the ghost loop, and seamlessly controlling the related combinatorics.
