Infrared problem in the Faddeev–Popov sector in Yang–Mills theory and perturbative gravity
In a broad class of spacetimes including de Sitter space, the Faddeev–Popov ghost propagator is infrared-divergent in both BRST-quantised Yang–Mills theory and BRST-quantised perturbative gravity. Introducing a mass term for infrared regularisation, one may delete an infrared-divergent term from the...
