Strange nucleon form factors: Solitonic approach to GMs , GEs , and and comparison with world data

Abstract

Abstract. We summarize the results of the chiral quark-soliton model (? 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 , and 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 ?p and ? scattering.
