Determination of the strange nucleon form factors

Abstract

The strange contribution to the electric and magnetic form factors of the nucleon is determined at a range of discrete values of $Q^2$ up to $1.4$ GeV${}^2$. This is done by combining recent lattice QCD results for the electromagnetic form factors of the octet baryons with experimental determinations of those quantities. The most precise result is a small negative value for the strange magnetic moment: $G_M^s(Q^2=0)=-0.07\pm 0.03{\mu }_N$. At larger values of $Q^2$ both the electric and magnetic form factors are consistent with zero to within $2$-sigma.
