Gauge-invariant resummation formalism for two-point correlation functions.
The consistent description of unstable particles, renormalons, or other Schwinger–Dysontype of solutions within the framework of perturbative gauge field theories necessitates the definition and resummation of off-shell Green’s functions, which must respect several crucial physical requirements. A formalism is presented for resummation of off-shell twopoint correlation functions, which is mainl...
متن کاملGauge-fixing parameter dependence of two-point gauge-variant correlation functions.
The gauge-fixing parameter ξ dependence of two-point gauge variant correlation functions is studied for QED and QCD. We show that, in three Euclidean dimensions, or for four-dimensional thermal gauge theories, the usual procedure of getting a general covariant gauge-fixing term by averaging over a class of covariant gauge-fixing conditions leads to a nontrivial gauge-fixing parameter dependence...
متن کاملCoulomb gauge Green functions and Gribov copies in SU(2) lattice gauge theory
We reconsider the lattice measurement of Green functions in Coulomb gauge, both in 2 + 1 and 3 + 1 dimensions, using an improved gauge fixing scheme. The influence of Gribov copies is examined and we find clear indications that Green functions are more strongly affected than previously assumed, in particular for low momenta. Qualitatively, our improved lattice results in the infra-red compare m...
متن کاملCorrelation functions in a cascading N=1 gauge theory
We study fluctuations around the warped conifold supergravity solution of Klebanov and Tseytlin [1], known to be dual to a cascading N = 1 gauge theory. Although this supergravity background is not asymptotically AdS, corresponding to a non-conformal field theory, it is possible to apply the usual methods of AdS/CFT duality to extract the high energy behavior of field theory correlators by solv...
متن کاملA generating functional for equal-time correlation functions
Our aim is to put the partially successful analytic noncovariant approaches to Coulomb gauge QCD on a firm and systematic basis. To this end, we develop a generating functional approach to the equal-time correlation functions. In fact, such a functional is given in terms of the vacuum wave functional, however, in a perturbative expansion of the equal-time correlation functions, the vacuum wave ...
