Description

Chiral perturbation theory (ChPT) is an effective field theory which can be applied in the low-energy regime of QCD describing the strong interactions. Heavy baryons, such as the $\Delta(1232)$ resonance, can be included in the theory and the desired physical quantities can be calculated in ChPT in terms of an expansion in small parameters such as the pion mass or small momenta. In this work, the form factors of the axial nucleon-delta transition are calculated using the complex mass renormalization scheme (CMS), which is suitable for unstable particles. The behavior of the form factors with respect to the transferred momentum Ais discussed, and the axial charge of the nucleon-delta transition is obtained as $C_5^A = 1.19$.
