Towards the glueball spectrum from unquenched lattice QCD
E. Gregory, A. Irving, B. Lucini +4
We use a variational technique to study heavy glueballs on gauge configurations generated with 2+1 flavours of ASQTAD improved staggered fermions. The variational technique include…
A study of the eta and eta' mesons with improved staggered fermions
Eric B. Gregory, Alan C. Irving, Christopher M. Richards +1
We report on a high statistics lattice QCD calculation of the mass of the eta and eta' mesons using ASQTAD improved staggered fermions. The calculation used two ensembles with diff…
Glueball mass measurements from improved staggered fermion simulations
Christopher M. Richards, Alan C. Irving, Eric B. Gregory +1
We present the first 2+1 flavour spectrum measurements of glueball states using high statistics simulations with improved staggered fermions. We find a spectrum consistent with que…
Pseudoscalar Flavor-Singlet Physics with Staggered Fermions
Eric B. Gregory, Alan Irving, Chris M. Richards +2
Accurately calculating the mass of flavor-singlet meson states from numerical lattice simulations is an important milestone for lattice QCD. Careful measurement of the full pseudos…
Methods for Pseudoscalar Flavour-Singlet Mesons with Staggered Fermions
Eric B. Gregory, Alan C. Irving, Chris M. Richards +1
We present the first 2+1 flavour lattice QCD calculations of pseudoscalar flavour-singlet propagators using improved staggered fermions. We explore the relevant techniques and disc…
Pseudoscalar flavor-singlets and staggered fermions
Eric B. Gregory, Alan C. Irving, Craig McNeile +1
The Asqtad improved staggered fermion formalism has been a valuable tool in successfully calculating the non-singlet parts of the hadronic spectrum. We are engaged in a project to…
