Non-perturbative BRST symmetry and the spectral structure of the ghost propagator
Shirley Weishi Li, Peter Lowdon, Orlando Oliveira +1
In BRST-quantised Yang-Mills theory the existence of BRST symmetry imposes significant constraints on the analytic structure of the continuum theory. In particular, the presence of…

The generalised infrared structure of the gluon propagator
Shirley Weishi Li, Peter Lowdon, Orlando Oliveira +1
Gauge theory correlators are potentially more singular in the infrared than those in non-gauge theories. We determine the implications that these singularities have on the spectrum…
