Analysis of a quenched lattice-QCD dressed-quark propagator
M. S. Bhagwat, M. A. Pichowsky, C. D. Roberts +1
Quenched lattice-QCD data on the dressed-quark Schwinger function can be correlated with dressed-gluon data via a rainbow gap equation so long as that equation's kernel possesses e…
Recent Advances in Dyson-Schwinger Studies
M. A. Pichowsky
There have been many demonstrations of the utility of the Dyson-Schwinger equations of QCD as a systematic, phenomenological framework for describing the perturbative and non-pertu…
Relativistic unitary description of pi pi scattering
M. A. Pichowsky, A. Szczepaniak, J. T. Londergan
A unitary framework based on the Bakamjian-Thomas construction of relativistic quantum mechanics is used to describe two-pion scattering from threshold to 1400 MeV. The framework p…
Quark exchange and quark dynamics in diffractive electroproduction
M. A. Pichowsky
A Dyson-Schwinger-based model of pomeron exchange is employed to calculate diffractive rho-, phi- and J/psi-meson electroproduction cross sections. It is shown that the magnitude o…
Electromagnetic form factors of light vector mesons
F. T. Hawes, M. A. Pichowsky
The electromagnetic form factors G_E(q^2), G_M(q^2), and G_Q(q^2), charge radii, magnetic and quadrupole moments, and decay widths of the light vector mesons rho^+, K^{*+} and K^{*…
Exclusive diffractive processes and the quark substructure of mesons
M. A. Pichowsky, T. -S. H. Lee
Exclusive diffractive processes on the nucleon are investigated within a model in which the quark-nucleon interaction is mediated by Pomeron exchange and the quark substructure of…
Pomeron exchange and exclusive electroproduction of rho-mesons in QCD
M. A. Pichowsky, T. -S. H. Lee
A Pomeron-exchange model of exclusive electroproduction of -mesons is examined using a dressed-quark propagator. It is shown that by representing the photon--meson-Pomeron co…
