Comment on ``Lattice QCD analysis of the strangeness magnetic moment of the nucleon''
Abstract
The recent chirally extrapolated result of Leinweber and Thomas [Phys. Rev. D {\bf 62}, 074505 (2000), or LT] for the nucleon strangeness form factor G_M^s(0)= -0.16 \pm 0.18 μ_N differs markedly from the earlier result -0.75 \pm 0.30 μ_N obtained by Leinweber [Phys. Rev. D {\bf 53}, 5115 (1996)] from the same lattice data. An unresolved problem in the LT analysis of lattice data is identified and addressed. A value of G_M^s(0) = -0.55 \pm 0.37 μ_N is obtained at R^s_d = 0.55 by extrapolating only the nucleon isoscalar lattice data.
