| Özet: | Title screen We apply the perturbative chiral quark model (PCQM) at one loop to analyse the axial form factor of the nucleon. This chiral quark model is based on an effective Lagrangian, where baryons are described by relativistic valence quarks and a perturbative cloud of Goldstone bosons as dictated by chiral symmetry. We apply the formalism to obtain analytical expressions for the axial form factor of the nucleon, which is given in terms of fundamental parameters of low-energy pion–nucleon physics (weak pion decay constant, strong pion–nucleon form factor) and of only one model parameter (radius of the nucleonic three-quark core).
