Structure and Flow of the Nucleon Eigenstates in Lattice QCD
M. Selim Mahbub, Waseem Kamleh, Derek B. Leinweber +2
A determination of the excited energy eigenstates of the nucleon, , , , is presented in full QCD using 2+1 flavor PACS-CS gauge configurations. The co…
Multi-Particle Baryon Spectroscopy
Adrian L. Kiratidis, Waseem Kamleh, Derek B. Leinweber +1
In Nature the excited states of the hadron spectrum appear as resonances. Consequently, there has been significant interest in studying the excited baryon spectrum using lattice QC…
The Influence of Instantons on the Quark Propagator
Amalie Trewartha, Waseem Kamleh, Derek Leinweber +1
We use over-improved stout-link smearing to investigate the presence and nature of instantons on the lattice. We find that smearing can remove short-range effects with little damag…
Low-lying Odd-parity States of the Nucleon in Lattice QCD
M. Selim Mahbub, Waseem Kamleh, Derek B. Leinweber +2
The world's first examination of the odd-parity nucleon spectrum at light quark masses in 2+1 flavor lattice QCD is presented. Configurations generated by the PACS-CS collaboration…
SU(3) centre vortices underpin confinement and dynamical chiral symmetry breaking
Elyse-Ann O'Malley, Waseem Kamleh, Derek Leinweber +1
The mass function of the nonperturbative quark propagator in SU(3) gauge theory shows only a weak dependence on the vortex content of the gauge configurations. Of particular note i…
Excited States of the Nucleon in 2+1 Flavor QCD
M. S. Mahbub, W. Kamleh, D. B. Leinweber +2
Recent developments on the determination of the spin-1/2 spectrum of the nucleon in full QCD are presented. Our focus is on the PACS-CS 2+1 flavor configurations made available thr…
