Vertex Sensitivity in the Schwinger-Dyson Equations of QCD
D. J. Wilson, M. R. Pennington
The non-perturbative gluon and ghost propagators in Landau gauge QCD are obtained using the Schwinger-Dyson equation approach. The propagator equations are solved in Euclidean spac…
The nature of the lightest scalar meson, its Nc behaviour and semi-local duality
J. R. Peláez, M. R. Pennington, J. Ruiz de Elvira +1
One-loop unitarized Chiral Perturbation Theory (UChPT) calculations, suggest a different Nc behaviour for the sigma or f0(600) and rho(770) mesons: while the rho meson becomes narr…
Are the Dressed Gluon and Ghost Propagators in the Landau Gauge presently determined in the confinement regime of QCD?
M. R. Pennington, D. J. Wilson
The Gluon and Ghost propagators in Landau gauge QCD are investigated using the Schwinger-Dyson equation approach. Working in Euclidean spacetime, we solve for these propagators usi…
Chiral Perturbation Theory, the expansion and Regge behaviour determine the structure of the lightest scalar meson
J. Ruiz de Elvira, J. R. Peláez, M. R. Pennington +1
The leading behaviour of Unitarised Chiral Perturbation Theory distinguishes the nature of the and the . At one loop order the is a meson, while the…
Structure of the lightest scalar meson from the 1/Nc expansion of Unitarized Chiral Perturbation Theory and Regge Theory
J. Ruiz de Elvira, J. R. Pelaez, M. R. Pennington +1
One-loop unitarized Chiral Perturbation Theory (UChPT) calculations, suggest a different Nc behaviour for the sigma or f_0(600) and rho(770) mesons: while the rho meson becomes nar…
Decay channels and charmonium mass-shifts
M. R. Pennington, D. J. Wilson
The discovery in the last few years of the and states of the extended charmonium family has highlighted the importance of the closeness of decay channels to an understan…
