Essential Strangeness in Nucleon Magnetic Moments

Abstract

Effective quark magnetic moments are extracted from experimental measurements as a function of the strangeness magnetic moment of the nucleon. Assumptions made in even the most general quark model analyses are ruled out by this investigation. Ab initio QCD calculations demand a non-trivial role for strange quarks in the nucleon. The effective moments from QCD calculations are reproduced for a strangeness magnetic moment contribution to the proton of 0.11 μN\mu_N, which corresponds to F2s(0)=0.33 μNF_2^s(0) = -0.33\ \mu_N.
