The effect of tree-level and mean-field improvement on the light-hadron spectrum in quenched QCD

UKQCD Collaboration, H. P. Shanahan, C. T. H. Davies +10

We compute the light hadron mass spectrum at beta=5.7 using the O(a) improved Sheikholeslami-Wohlert (SW) fermion action with two choices of the clover coefficient: the classical v…
