We present some early results from a high statistics study of the scalar and pseudoscalar singlet sectors of lattice QCD using 2+1 flavours of Asqtad improved staggered fermions. The use of the Asqtad action has allowed us to generate an unprecedented number of configurations at 2 lattice spacings which on completion we hope will give us a significantly improved view of both the scalar and pseudoscalar singlet sectors.

Physics of $\eta'$ with rooted staggered quarks
The quark-mass dependence of the eta in the Schwinger model, which -- like the eta-prime in QCD -- becomes massive through the axial anomaly, is studied on the lattice with N_f=0,1,2. StaggeredExpand

How, with modern high-performance computing resources, even small scientific groups can generate huge volumes of valuable scientific data and how grid technology can be used to manage, publish, share and curate these data is illustrated. Expand


The Eta-prime Meson with Staggered Fermions
We have computed the eta-prime pseudoscalar octet mass splitting using staggered fermions on both dynamical and quenched gauge configurations. We have used Wuppertal smeared operators to reduceExpand
Scalar Meson Spectroscopy with Lattice Staggered Fermions
With sufficiently light up and down quarks the isovector ( a0) and isosinglet (f0) scalar meson propagators are dominated at large distance by two-meson states. In the staggered fermion formulationExpand
Chiral anomalies and rooted staggered fermions
A popular approximation in lattice gauge theory is an extrapolation in the number of fermion species away from the four fold degeneracy natural with the staggered fermion formulation. I show that theExpand
Lattice gauge theory with staggered fermions: how, where, and why (not)
Many results from lattice QCD of broad importance to particle and nuclear physics are obtained with 2+1 flavors of staggered sea quarks. In the continuum limit, staggered fermions yield four species,Expand
