Scientific paper

We report on the contributions to the nucleon weak magnetic and electric form factors arising from isospin-breaking form factors. The relativized quark model used in the calculations includes isospin impurities in the large basis nucleon wavefunctions and uses constituent quark currents with both Pauli and Dirac components. Significant contributions are found to arise from the Pauli component when it is interpreted as arising from pion-baryon loops. Including these pion cloud contributions reduces the strange magnetic form factor extracted from the recent SAMPLE measurement of the proton's weak neutral magnetic form factor at low Q^2 by 35 to 52%.
