Abstract.
We summarize the results of the chiral quark-soliton model (χ QSM) concerning basically all form factors necessary to interpret the present data of the parity-violating electron scattering experiments SAMPLE, HAPPEX, A4 and G0. The results particularly focus on the recently measured asymmetries and the detailed data for various combinations of G M s , G E s , \( \tilde{{G}}_{{A}}^{{p}}\) and \( \tilde{{G}}_{{A}}^{{n}}\) at Q 2 = 0.1 GeV^2. The calculations yield positive strange magnetic and electric form factors and a negative axial vector one, all being rather small. The results are very close to the combined experimental world data from parity-violating electron scattering and elastic νp and ¯ scattering.
