Perez Rubio, Paula and Sint, Stefan (2011) The running of the Schrödinger functional coupling from four‐flavour lattice QCD with staggered quarks. In: THE IX INTERNATIONAL CONFERENCE ON QUARK CONFINEMENT AND THE HADRON SPECTRUM—QCHS IX , 30 August–3 September 2010 , Madrid, (Spain).
We present preliminary results for the running coupling in the Schrödinger functional scheme in QCD with four flavours. A single‐component staggered quark field is used on lattices of size (L/a)3×(L/a±1). This provides us with 2 different regularisations of the same renormalized coupling, and thus some control over the size of lattice artefacts. These are found to be comparatively large, calling for a more refined analysis, which still remains to be done.
