Low-lying odd-parity nucleon resonances as quark-model like states
Curtis D. Abell, Derek B. Leinweber, Zhan-Wei Liu +2
Recent lattice QCD results for the low-lying odd-parity excitations of the nucleon near the and resonance positions have revealed that the lattice QCD s…
Charge Symmetry Violation in the Electromagnetic Form Factors of the Proton
P. E. Shanahan, R. Horsley, Y. Nakamura +7
Experimental tests of QCD through its predictions for the strange-quark content of the proton have been drastically restricted by our lack of knowledge of the violation of charge s…
Scale setting, sigma terms and the Feynman-Hellman theorem
P. E. Shanahan, A. W. Thomas, R. D. Young
The authors recently presented new values for the octet baryon sigma terms. These were extracted using the Feynman-Hellman theorem from a chiral perturbation theory fit to octet ba…
Charge Symmetry Breaking in Parton Distribution Functions from Lattice QCD
R. Horsley, Y. Nakamura, D. Pleiter +7
By determining the quark momentum fractions of the octet baryons from N_f=2+1 lattice simulations, we are able to predict the degree of charge symmetry violation in the parton dist…
An analysis of the nucleon spectrum from lattice partially-quenched QCD
W. Armour, C. R. Allton, D. B. Leinweber +2
The chiral extrapolation of the nucleon mass, M_n, is investigated using data coming from 2-flavour partially-quenched lattice simulations. A large sample of lattice results from t…
Strange Electric Form Factor of the Proton
D. B. Leinweber, S. Boinepalli, A. W. Thomas +5
By combining the constraints of charge symmetry with new chiral extrapolation techniques and recent low-mass quenched lattice QCD simulations of the individual quark contributions…
