Abstract
We discuss symmetry breaking in the weak magnetism form factors for
the semileptonic octet baryon decays. In the chiral quark model, the
symmetry breaking can be accounted for in the masses and the quark spin
polarizations can take on more general values due to Goldstone boson
depolarization. Here we clarify some features of the chiral quark model
prediction for the weak magnetism and compare to the corresponding result
of the chiral quark soliton model.
