Matrix elements and baryon spectroscopy from unquenched lattice QCD with improved staggered quarks
Eric B. Gregory, Alan C. Irving, Craig McNeile +2
We look for the effect of open decay channels on the masses of baryons in unquenched lattice QCD. We apply variational smearing using fuzzed basis states to a staggered nucleon ope…
Towards measuring the eta' mass with N_f=2+1 staggered fermions
Eric B. Gregory, Alan Irving, Craig McNeile +2
Because the propagators of flavor-singlet states incorporate disconnected diagrams, they are uniquely sensitive to any differences in the actions governing sea and valence fermions…
Scalar glueball and meson spectroscopy in unquenched lattice QCD with improved staggered quarks
Eric B. Gregory, Alan C. Irving, Craig C. McNeile +2
We present results of an exploratory study of singlet scalar states in unquenched QCD using both glueball and meson operators. Results for non-singlet non-strange scalar mesons are…
Pseudoscalar singlet physics with staggered fermions
Eric B. Gregory, Alan C. Irving, Craig McNeile +2
We report on progress in measuring disconnected correlators associated with pseudoscalar flavor-singlet mesons. This will eventually allow us to compute the masses of the eta and e…
Exact 2+1 flavour RHMC simulations
M. A. Clark, A. D. Kennedy, Z. Sroczynski
We consider the Rational Hybrid Monte Carlo algorithm for performing exact 2+1 flavour fermion simulations. The specific cases of ASQTAD and domain wall fermions are considered. We…
On the scaling of computational particle physics codes on cluster computers
Z. Sroczynski, N. Eicker, Th. Lippert +2
Many appplications in computational science are sufficiently compute-intensive that they depend on the power of parallel computing for viability. For all but the "embarrassingly pa…
