Comment on ``A New Symmetry for QED'' and ``Relativistically Covariant Symmetry in QED''

TL;DR

This paper clarifies that recently discovered symmetries in quantum electrodynamics are actually non-local forms of the well-established BRST symmetry, providing a reinterpretation of these symmetries.

Contribution

It demonstrates that recent symmetries in QED are equivalent to non-local BRST symmetry, offering a new perspective on their nature.

Findings

Recent QED symmetries are non-local BRST symmetries

Provides reinterpretation of symmetry structures in QED

Bridges new symmetries with established BRST framework

Abstract

We show that recently found symmetries in QED are just non-local versions of standard BRST symmetry.
