Description
We have calculated the axial-vector form factors for the hyperon semileptonic decays $B_i \rightarrow B_f l \bar{\nu}$ in the chiral constituent quark model ($\chi$CQM). The decays considered here are the strangeness changing as well as strangeness conserving semileptonic decays of the hyperons. The conventional dipole form of parametrization has been used to analyse the $Q^2$ dependence of the axial-vector form factors ($g_i^{B_iB_f}(Q^2)$) as well their decay constants. The results have been compared with the experimental data and are found to be in good agreement with existing available data.
