Aspects of Precision Calculations of Nucleon Generalized Form Factors with Domain Wall Fermions on an Asqtad Sea
J. D. Bratt, R. G. Edwards, M. Engelhardt +13
In order to advance lattice calculations of moments of unpolarized, helicity, and transversity distributions, electromagnetic form factors, and generalized form factors of the nucl…
Light hadron spectroscopy using domain wall valence quarks on an Asqtad sea
Andre Walker-Loud, Huey-Wen Lin, Kostas Orginos +15
We calculate the light hadron spectrum in full QCD using two plus one flavor Asqtad sea quarks and domain wall valence quarks. Meson and baryon masses are calculated on a lattice o…
Chiral extrapolation of g_A with explicit Delta(1232) degrees of freedom
M. Procura, B. U. Musch, T. R. Hemmert +1
An updated and extended analysis of the quark mass dependence of the nucleon's axial vector coupling constant g_A is presented in comparison with state-of-the-art lattice QCD resul…
Nucleon mass: from lattice QCD to the chiral limit
M. Procura, B. U. Musch, T. Wollenweber +2
Previous extrapolations of lattice QCD results for the nucleon mass to the physically relevant region of small quark masses, using chiral effective field theory, are extended and e…
Quark mass dependence of nucleon mass and axial-vector coupling constant
M. Procura, B. U. Musch, T. R. Hemmert +1
We present an updated analysis of the quark mass dependence of the nucleon mass and nucleon axial-vector coupling g_A, comparing different formulations of SU(2) Baryon Chiral Effec…
Nucleon mass, sigma term and lattice QCD
M. Procura, T. R. Hemmert, W. Weise
We investigate the quark mass dependence of the nucleon mass M_N. An interpolation of this observable, between a selected set of fully dynamical two-flavor lattice QCD data and its…
