Power corrections to symmetric point vertices in Gribov-Zwanziger theory
arXiv:1210.5962 · doi:10.1103/PhysRevD.86.105029
Abstract
The 3-point vertices of QCD are examined at the symmetric subtraction point at one loop in the Landau gauge in the presence of the Gribov mass, gamma. They are expanded in powers of gamma^2 up to dimension four in order to determine the order of the leading correction. As well as analysing the pure Gribov-Zwanziger Lagrangian, its extensions to include localizing ghost masses are also examined. For comparison a pure gluon mass term is also considered.
