Axial Vector Couplings of the Nucleon in Chiral Quark Model Incorporating U(1)A Anomaly Effects
Abstract
Renormalization of the axial vector currents due to Goldstone loops is studied in a simple extension of Manohar - Georgi chiral quark model which incorporates U(1)A anomaly effects. The polarized strage quark sea in the polarized nucleon results from different renormalization of the flavor singlet and octet currents and is in reasonable agreement with the experiment.
