Quantization of Yang-Mills Theory in de Sitter Spacetime
arxiv(2023)
摘要
In this paper, we analyze the quantization of Yang-Mills theory in the de
Sitter spacetime. It is observed that the Faddeev–Popov ghost propagator is
divergent in this spacetime. However, this divergence is removed by using an
effective propagator, which is suitable for perturbation theory. To show that
the quantization of Yang–Mills theory in the de Sitter is consistent, we
quantize it using first-class constraints in the temporal gauge. We also
demonstrate that this is equivalent to quantizing the theory in the Lorentz
gauge.
