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

Antonio Silva, Hyun-Chul Kim, Diana Urbano, Klaus Goeke

چکیده

We investigate three different axial-vector form factors of the nucleon, GA, G 3 A, G 8 A, within the framework of the SU(3) chiral quark-soliton model, emphasizing their strangeness content. We take into account the rotational 1/Nc and linear strange quark (ms) contributions using the symmetryconserving 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.

We calculate the axial form factor in the chiral quark soliton (semibosonized Nambu Jona-Lasinio) model using the semiclassical quantization scheme in the next to leading order in angular velocity. The obtained axial form factor is in a good absolute (without additional scaling)

The weak vector and axial-vector form factors have been investigated for the semi-leptonic octet baryon decays in the chiral constituent quark model with configuration mixing (χCQMconfig). The effects of SU(3) symmetry breaking and configuration mixing have also been investigated

Abstract The strange vector form factors are evaluated for Q2 = 0 and Q2 = 1 GeV in the framework of the SU(3) chiral quark-soliton model (or semi-bosonized SU(3) Nambu-Jona-Lasinio model). The rotational 1/Nc and ms corrections are taken into account up to linear order. The mean
