A Renormalizable and Unitary Approach to Quantum Gravity
arXiv:2605.17817
Abstract
A Lagrange multiplier field restricts the quantum corrections to the Einstein-Hilbert action at one-loop order, yielding a model that is renormalizable and unitary while reproducing the Einstein field equations in the classical limit.
