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…
