WebJan 3, 2002 · The mass of the D s meson in lattice units is M D s ≃0.73 (3), where we use a −1 (m K ∗ )=2.7 (1) GeV. Thus the charm-quark mass is to be found through an interpolation between the results for κ Q =0.125 and κ Q =0.122. Notice that in Table 2 we give also the results for a larger quark mass corresponding to κ Q =0.119. fitland mill restaurant
