Nucleon Structure with Domain Wall Fermions at a = 0.084 fm
S. N. Syritsyn, J. D. Bratt, M. F. Lin +13
We present initial calculations of nucleon matrix elements of twist-two operators with 2+1 flavors of domain wall fermions at a lattice spacing a = 0.084 fm for pion masses down to…
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…
Glueball matrix elements: a lattice calculation and applications
Harvey B. Meyer
We compute the matrix elements of the energy-momentum tensor between glueball states and the vacuum in SU(3) lattice gauge theory and extrapolate them to the continuum. These matri…
Energy-momentum tensor correlators and spectral functions
Harvey B. Meyer
We calculate the thermal Euclidean correlators and the spectral functions of the energy-momentum tensor for pure gauge theories, including at non-zero spatial momentum, at leading…
