Independence of , Poincare Invariance and the Non-Conservation of Helicity
Gerald A. Miller, Michael R. Frank
A relativistic constituent quark model is found to reproduce the recent data regarding the ratio of proton form factors, . We show that imposing Poincare invaria…
Nucleon form factors and a nonpointlike diquark
J. C. R. Bloch, C. D. Roberts, S. M. Schmidt +2
Nucleon form factors are calculated on q^2 in [0,3] GeV^2 using an Ansatz for the nucleon's Fadde'ev amplitude motivated by quark-diquark solutions of the relativistic Fadde'ev equ…
Covariant equations for the three-body bound state
Alfred Stadler, Franz Gross, Michael Frank
The covariant spectator (or Gross) equations for the bound state of three identical spin 1/2 particles, in which two of the three interacting particles are always on shell, are dev…
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…
The hadron-quark transition with a lattice of nonlocal confining solitons
Charles W. Johnson, George Fai, Michael R. Frank
We use a lattice of nonlocal confining solitons to describe nuclear matter in the Wigner-Seitz approximation. The average density is varied by changing the size of the Wigner-Seitz…
Low-energy QCD: Chiral coefficients and the quark-quark interaction
M. R. Frank, T. Meissner
A detailed investigation of the low-energy chiral expansion is presented within a model truncation of QCD. The truncation allows for a phenomenological description of the quark-qua…
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…
Relativistic models for quasielastic \ at large momentum transfers
Hungchong Kim, C. J. Horowitz, M. R. Frank
Inclusive quasielastic response functions are calculated for electron scattering in a relativistic model including momentum dependent scalar and vector mean fields. The momentum de…
Gauge Invariance and the Electromagnetic Current of Composite Pions
M. R. Frank, P. C. Tandy
The Global Color-symmetry Model of QCD is extended to deal with a background electromagnetic field and the associated conserved current is identified for composite pion…
