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.
