Spatial diquark correlations in a hadron
Jeremy Green, Michael Engelhardt, John Negele +1
Using lattice QCD, a diquark can be studied in a gauge-invariant manner by binding it to a static quark in a heavy-light-light hadron. We compute the simultaneous two-quark density…
Strangeness in the nucleon from a mixed action calculation
Michael Engelhardt
The contributions of strange quarks to the nucleon mass and the nucleon spin are investigated in a mixed action scheme employing domain wall valence quarks and quark loops on MILC…
Progress toward the chiral regime in lattice QCD calculations of the neutron electric polarizability
Michael Engelhardt
The static electric polarizability of the neutron is evaluated using domain-wall valence quarks on a MILC asqtad sea quark ensemble corresponding to a pion mass of m_pi = 357 MeV.…
Nucleon structure from mixed action calculations using 2+1 flavors of asqtad sea and domain wall valence fermions
LHPC Collaboration, Jonathan D. Bratt, Robert G. Edwards +13
We present high statistics results for the structure of the nucleon from a mixed-action calculation using 2+1 flavors of asqtad sea and domain wall valence fermions. We perform ext…
