Glimpsing Colour in a World of Black and White
M. R. Pennington
The past 40 years have taught us that nucleons are built of constituents that carry colour charges with interactions governed by Quantum Chromodynamics (QCD). How experiments (past…
Exciting Baryons: now and in the future
M. R. Pennington
This is the final talk of NSTAR2011 conference. It is not a summary talk, but rather a looking forward to what still needs to be done in excited baryon physics. In particular, we n…
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…
