Axial-vector form factors of the light, singly and doubly charmed baryons in the chiral quark constituent model

Abstract

The axial-vector form factors of the light, singly and doubly charmed baryons are investigated in the framework of $SU(4)$ chiral constituent quark model. The axial-vector form factors having physical significance correspond to the generators of the $SU(4)$ group with flavor singlet $\lambda^{0}$, flavor isovector $\lambda^{3}$, flavor hypercharge $\lambda^{8}$ and flavor charmed $\lambda^{15}$ combinations of axial-vector current at zero momentum transfer. In order to further understand the $Q^2$ dependence of these charges, we have used the conventionally established dipole form of parametrization.
