TL;DR
This paper proves that a new formulation of the Gribov-Zwanziger action maintains renormalizability at all orders despite having a spontaneously broken BRST symmetry, advancing understanding of gauge theories.
Contribution
It provides an all-orders algebraic proof of the renormalizability of a novel Gribov-Zwanziger formulation with spontaneously broken BRST symmetry.
Findings
The formulation is multiplicatively renormalizable at all orders.
BRST symmetry is spontaneously broken but remains consistent.
The proof confirms the theoretical consistency of the approach.
Abstract
An all orders algebraic proof of the multiplicative renormalizability of the novel formulation of the Gribov-Zwanziger action proposed in Phys. Rev. D 86, 045005 (2012) [arXiv:1205.3934], and allowing for an exact but spontaneously broken BRST symmetry, is provided.
