Scaling of nonperturbatively O(a) -improved Wilson fermions: Hadron spectrum, quark masses, and decay constants

Year: 1998

Type: article

Abstract: We compute the hadron mass spectrum, the quark masses, and the meson decay constants in quenched lattice QCD with nonperturbatively $O(a)$-improved Wilson fermions. The calculations are done for two values of the coupling constant $\ensuremath{\beta}=6.0$ and 6.2, and the results are compared with the predictions of ordinary Wilson fermions. We find that the improved action reduces lattice artifacts as expected.
