Axial-vector form factors of the nucleon within the chiral quark-soliton model and their strange components

We investigate three different axial-vector form factors of the nucleon, G{sub A}{sup 0}, G{sub A}{sup 3}, G{sub A}{sup 8}, within the framework of the SU(3) chiral quark-soliton model, emphasizing their strangeness content. We take into account the rotational 1/N{sub c} and linear strange quark (m{sub s}) contributions using the symmetry-conserving SU(3) quantization and assuming isospin symmetry. The strange axial-vector form factor is also obtained and they all are discussed in the context of the parity-violating scattering of polarized electrons off the nucleon and its relevance to the strange vector form factors.
