The UA(1) problem and the role of correlated q qbar exchange in effective theories of QCD
M. R. Frank, T. Meissner
The combined absence of physical realizations of the UA(1) symmetry possessed by the classical QCD action in the chiral limit, and of an isoscalar Goldstone boson associated with i…
On the calculation of hadron form factors from Euclidean Dyson-Schwinger equations
M. Burkardt, M. R. Frank, K. L. Mitchell
We apply Euclidean time methods to phenomenological Dyson-Schwinger models of hadrons. By performing a Fourier transform of the momentum space correlation function to Euclidean tim…
Low-Energy QCD: Chiral Coefficients, UA(1)-Breaking and the Quark-Quark Interaction
Thomas Meissner, Michael Frank
A detailed investigation of the low-energy chiral expansion is presented within a model truncation of QCD. The model dependence of the chiral coefficients is tested for several for…
Off-Shell Axial Anomaly via the γ^* π^0 -> γTransition
M. R. Frank, K. L. Mitchell, C. D. Roberts +1
The form factor, including the extension off the pion mass-shell, is obtained from a generalized impulse approximation within a QCD-based model field theory…
