Extraction of P11 Resonance from pi-N Data and Its Stability
S. X. Nakamura, H. Kamano, T. -S. H. Lee +1
An important question about resonance extraction is how much resonance poles and residues extracted from data depend on a model used for the extraction, and on the precision of dat…
Moments of Isovector Quark Distributions in Lattice QCD
W. Detmold, W. Melnitchouk, A. W. Thomas
We investigate the connection of lattice calculations of moments of isovector parton distributions to the physical regime through extrapolations in the quark mass. We consider the…
Bethe-Salpeter equation and a nonperturbative quark-gluon vertex
A. Bender, W. Detmold, C. D. Roberts +1
A Ward-Takahashi identity preserving Bethe-Salpeter kernel can always be calculated explicitly from a dressed-quark-gluon vertex whose diagrammatic content is enumerable. We illust…
Dependence of the Chiral Symmetry Restoration Transition on the Quark Self-Energy Kernel
A. Bender, W. Detmold, A. W. Thomas
The dependence of the dressed quark propagator on the quark chemical potential is investigated in various models based on the Dyson-Schwinger equations. We find that the critical c…
A New Slant on Hadron Structure
W. Detmold, D. B. Leinweber, W. Melnitchouk +2
Rather than regarding the restriction of current lattice QCD simulations to quark masses that are 5--10 times larger than those observed, we note that this presents a wonderful opp…
