Computing Nucleon Charges with Highly Improved Staggered Quarks
Yin Lin, Aaron S. Meyer, Steven Gottlieb +4
This work continues our program of lattice-QCD baryon physics using staggered fermions for both the sea and valence quarks. We present a proof-of-concept study that demonstrates, f…
Nucleon and Baryon Masses with All-HISQ Fermions at the Physical Point
Ciaran Hughes, Yin Lin, Aaron S. Meyer
We present the results of the nucleon and baryon masses using staggered action for both valence and sea quarks. Three ensembles with the physical pion mass at approximate latti…
Exploring S-Wave Threshold Effects in QCD: A Heavy-Light Approach
Estia Eichten, Ciaran Hughes
QCD exhibits complex dynamics near S-wave two-body thresholds. For light mesons, we see this in the failure of quark models to explain the and masses. For c…
Nucleon Mass with Highly Improved Staggered Quarks
Yin Lin, Aaron S. Meyer, Ciaran Hughes +3
We present the first computation in a program of lattice-QCD baryon physics using staggered fermions for sea and valence quarks. For this initial study, we present a calculation of…
Improving the Kinetic Couplings in Lattice Non-Relativistic QCD
Christine T. H. Davies, Judd Harrison, Ciaran Hughes +3
We improve the non-relativistic QCD (NRQCD) action by comparing the dispersion relation to that of the continuum through in perturbation theory. The one-loop mat…
New methods for B meson decay constants and form factors from lattice NRQCD
C. Hughes, C. T. H. Davies, C. J. Monahan
We determine the normalisation of scalar and pseudoscalar current operators made from non-relativistic quarks and Highly Improved Staggered light quarks in lattice Quantum Chro…
