Critical behavior of a four-point Schwinger-Dyson equation.
We study the Schwinger-Dyson equation associated with a chirality-changing fermion 4-point function in a strongly-coupled U(1) gauge theory. After making appropriate simpliications, we solve the equation numerically via a relaxation method. Our analysis provides an estimate of the critical coupling and it gives some indication as to the general momentum dependence of the 4-point function.
متن کاملDyson - 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 کاملQuark Spectrum above the Critical Temperature from Schwinger-dyson Equation
We investigate a spectrum of a fermion, which we call a quark, above the critical temperature of the chiral phase transition in a gauge theory using the Schwinger-Dyson (SD) equation. The SD equation enables us to study the spectrum over a wide range of the gauge coupling. It is shown that the quark spectrum has two sharp peaks which correspond to the normal quasi-quark and the plasmino and is ...

متن کاملFour-loop Dyson-Schwinger-Johnson anatomy
Dyson-Schwinger equations are used to evaluate the 4-loop anomalous dimensions of quenched QED in terms of finite, scheme-independent, 3-loop integrals. Three of the results serve as strong checks of terms from scheme-dependent 4-loop QCD calculations. The fourth, for the anomalous dimension of ψσμνψ, was previously known only to 2-loop order. The 4-loop beta function has 24 unambiguous terms. ...
