Quark axial coupling quenching and nucleon coupling constants
Description
The nucleon axial and pion-nucleon isobar coupling constants are calculated in a non-relativistic quark model for baryons with a pion cloud. We emphasized in this letter one possible way by which the experimental values are reproduced, namely the quenching of the quark axial coupling constant. This mechanism is consistent with the traditional naive quark model approach. (orig.)
