摘要
In this talk, we revisit the strange vector form factors of the nucleon within the framework of the SU(3) chiral quark-soliton model. We employ in this new work the prescription of the SU(3) quantization in order to remedy the charge problem arising from the nonlocality in time. We compute the neutral weak and strange vector form factors. We also incorporate two different asymptotics of the soliton field: pion and kaon tails. The results turn out to be compatible with the recent experimental data from the SAMPLE and HAPPEX collaborations. We also present the prediction for the A4 experiment.
