Description

We summarize the results of the chiral quark-soliton model (χQSM) 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 GMs, GEs, GAp and GAn at Q2=0.1 GeV2. 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 νanti p scattering. (orig.)
