Estimating the Unquenched Strange Quark Mass from the Lattice Axial Ward Identity
M. Göckeler, R. Horsley, A. C. Irving +5
We present a determination of the strange quark mass for two flavours (nf=2) of light dynamical quarks using the axial Ward identity. The calculations are performed on the lattice…
A Determination of the Lambda Parameter from Full Lattice QCD
M. Göckeler, R. Horsley, A. C. Irving +4
We present a determination of the QCD parameter Lambda in the quenched approximation (n_f=0) and for two flavours (n_f=2) of light dynamical quarks. The calculations are performed…
Determination of Light and Strange Quark Masses from Full Lattice QCD
M. Göckeler, R. Horsley, A. C. Irving +4
We compute the light and strange quark masses m_l = (m_u+m_d)/2 and m_s, respectively, in full lattice QCD with N_f=2 flavors of light dynamical quarks. The renormalization constan…
Improved Wilson QCD simulations with light quark masses
CR Allton, A Hart, D Hepburn +5
We present results from simulations using 2 flavours of O(a)-improved Wilson quarks whose masses are about 1/3 of the physical strange quark mass. We present new data on the mass o…
Progress in building an International Lattice Data Grid
A. C. Irving, R. D. Kenway, C. M. Maynard +1
We report on progress in setting up the International Lattice Data Grid. We describe the aims and objectives of the ILDG, what has been achieved during its first year of activity a…
