Determination of the Strange Nucleon Form Factors
Determination of the Strange Nucleon Form Factors
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 a recent analysis of lattice QCD results for the electromagnetic form factors of the octet baryons with experimental de...

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 a recent analysis of 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: $G^s_M(Q^2=0)=−0.07±0.03μN$. At larger values of $Q^2$ both the electric and magnetic form factors are consistent with zero to within 2 standard deviations. |
