TL;DR
This paper demonstrates that in a simplified Yang-Mills model, negative norm states can be BRST invariant and generated solely from gluons, highlighting a subtle aspect of gauge theories.
Contribution
It reveals that negative norm BRST singlet states can be created from gluons alone in a simplified Yang-Mills framework.
Findings
Negative norm states are BRST invariant.
Such states can be generated from gluons.
Implications for gauge theory quantization.
Abstract
Negative norm Hilbert space state vectors can be BRST invariant, we show in a simplified Y-M model that such states can be created by starting with gluons only.
