In Table 2, second column, fourth row, the factor of 2 should not be there. In Table 4, second column, fourth row, replace −0.08 by −0.04. In Eq.(8d) replace r 3 by 2 r 3.

In contrast to Ref. R. F. Lebed, Phys. Rev. D 67 (2003) 016002 [26]} we predict here r 2Λ > 0. This is due to our inclusion of SU(3) flavor symmetry breaking in the one-quark term in Eq.(3).
