Abstract
We study the weak vector and axial-vector form factors of first- and
second-class currents for the semileptonic octet baryon decays in the
spirit of the chiral quark model. Our results for the weak magnetism
form factors are consistent with the conserved vector current (CVC)
results. The induced pseudotensor form factors, which are highly model
dependent, are small. The overall performance of the chiral quark
model is quite good and in general agreement with existing
experimental data.
