Scalar condensate and light quark masses from overlap fermions
Pilar Hernandez, Karl Jansen, Laurent Lellouch +1
We have studied pseudoscalar correlation functions computed using the overlap operator. Within the accuracy of our calculation we find that the quark mass dependence agrees with th…
Is the up-quark massless?
UKQCD Collaboration, A. C. Irving, C. McNeile +3
We report on determinations of the low-energy constants alpha5 and alpha8 in the effective chiral Lagrangian at O(p^4), using lattice simulations with N_f=2 flavours of dynamical q…
Effects of non-perturbatively improved dynamical fermions in QCD at fixed lattice spacing
UKQCD Collaboration, C. R. Allton, S. P. Booth +17
We present results for the static inter-quark potential, lightest glueballs, light hadron spectrum and topological susceptibility using a non-perturbatively improved action on a $1…
Non-perturbative renormalization of the quark condensate in Ginsparg-Wilson regularizations
Pilar Hernandez, Karl Jansen, Laurent Lellouch +1
We present a method to compute non-perturbatively the renormalization constant of the scalar density for Ginsparg-Wilson fermions. It relies on chiral symmetry and is based on a ma…
First results on the running coupling in QCD with two massless flavours
Achim Bode, Roberto Frezzotti, Bernd Gehrmann +11
We report on the non-perturbative computation of the running coupling of two-flavour QCD in the Schr"odinger functional scheme. The corresponding Lambda-parameter, which describes…
