Bryce DeWitt, Carmen Molina-Paris (University of Texas at Austin)
TL;DR
This paper introduces a gauge-invariant quantum effective action for gauge field theories that does not depend on gauge fixing or ghost determinants, simplifying the quantization process.
Contribution
It presents a novel construction of a gauge-invariant effective action that eliminates the need for gauge fixing and ghost determinants in gauge theories.
Findings

Simplifies quantization of gauge theories.
Potentially reduces computational complexity in gauge theory calculations.
Abstract
A quantum effective action for gauge field theories is constructed that is gauge invariant and independent of the choice of gauge breaking terms and the ghost determinant.
