چکیده
Abstract Effective mass and energy are investigated using the Schwinger–Dyson equation (SDE) in complex plane. As simple examples, we solve SDE for (1+1)-dimensional model strongly coupled quantum electrodynamics (QED). We also study some properties of effective

Dyson - Schwinger Equation Studies
The dichotomy of the pion as QCD's Goldstone mode and a bound state of massive constituents is easily understood using the Dyson-Schwinger equations. That provides the foundation for an efficacious phenomenology, which correlates the pion's charge radius and electromagnetic form factor with its valence quark distribution function; and simultaneously provides a Poincaré covariant description of ...

متن کاملNonlinear effects in Schwinger-Dyson Equation
We study nonlinear effects in the QED ladder Schwinger-Dyson(SD) equation. Without further approximations, we show that all nonlinear effects in the ladder SD equation can be included in the effective couplings and how a linear approximation works well. The analyses is generalized in the case of the improved ladder calculation with the Higashijima-Miransky approximation. The dynamical symmetry ...
متن کاملSolving the Gluon Dyson–Schwinger Equation in the Mandelstam Approximation
Truncated Dyson–Schwinger equations represent finite subsets of the equations of motion for Green’s functions. Solutions to these non–linear integral equations can account for non–perturbative correlations. We describe the solution to the Dyson– Schwinger equation for the gluon propagator of Landau gauge QCD in the Mandelstam approximation. This involves a combination of numerical and analytic ...
