THE G(A) PROBLEM IN HEDGEHOG SOLITON MODELS REVISITED

It is widely known that the considerable underestimation of the nucleo n axial-vector coupling constant g(A) is an undesirable common feature of soliton models of the nucleon based on the so-called 'hedgehog'' c onfiguration. This fundamental physical quantity is reanalyzed within the framework of the chiral quark soliton model. The path integral qua ntization based on the cranking procedure leads to a systematic power series expansion in the Coriolis coupling (which scales as 1/N(c)) ind uced by the isorotation of the hedgehog mean field. We find that an im portant 1/N(c) correction exists in this scheme and it greatly improve s the situation for the g(A) problem.
