Nonperturbative propagators in quantum chromodynamics.

چکیده
Leading nonperturbative corrections to the quark and gluon propagators are derived following the assumption that the nonperturbative QCD vacuum can be described in terms of non-vanishing vacuum expectation values for the composite operators [T&I and [GEY]. Th e nonperturbative quark propagator can be described in terms of a running quark mass and a running normalization function. These quantities are shown to be gauge independent. The nonperturbative gluon propagator can be described in terms of a running gauge parameter and a running normalization function.

Spectral density constraints in quantum field theory
Determining the structure of spectral densities is important for understanding the behavior of any quantum field theory (QFT). However, the exact calculation of these quantities often requires a full nonperturbative description of the theory, which for physically realistic theories such as quantum chromodynamics (QCD) is currently unknown. Nevertheless, it is possible to infer indirect informat...
متن کاملRenormalization flow of Yang-Mills propagators
We study Landau-gauge Yang-Mills theory by means of a nonperturbative vertex expansion of the quantum effective action. Using an exact renormalization group equation, we compute the fully dressed gluon and ghost propagators to lowest nontrivial order in the vertex expansion. In the mid-momentum regime, p2 ∼ O(1)GeV, we probe the propagator flow with various ansätze for the threeand four-point c...
متن کاملA New Approach to Perturbative Theory in the Nonperturbative Qcd Vacuum
Using stochastic quantization method [1], we derive gauge–invariant equations, connecting multilocal vacuum correlators of nonperturbative field configurations, immersed into the quantum background. Three alternative methods of stochastic regularization of these equations are suggested, and the corresponding regularized propagators of a background field are obtained in the lowest order of pertu...
متن کاملThe High-Temperature Phase of Landau-Gauge Yang-Mills Theory
The properties of the high-temperature phase of Yang-Mills theory in Landau gauge are investigated by extending an earlier study on the infinite-temperature limit to finite temperatures. To this end the Dyson-Schwinger equations for the propagators of the gluon and the Faddeev-Popov ghost are solved analytically in the infrared and numerically at non-vanishing momenta. Gluons, polarized transve...
