On the origin of the gA problem in the Skyrme model

The recently discovered first order rotational correction to the nucleon axial-vector coupling constant gA within the framework of the chiral quark soliton model appears to provide us with an unexpectedly simple solution to the long-standing gA problem in the Skyrme model. A prominent feature of this special type of 1Nc correction is that the corresponding effect is entirely missing in the Skyrme model. We try to clarify the underlying mathematical reason why such a crucial difference appears between these two intimately-connected effective theories of baryons.
