\begin{document}$ \Xi^{(')}_{c}\to\Xi+e^+\nu_e $\end{document} may provide further information about the inner structure of charmed baryons. Moreover, by studying such processes, one can better determine the form factors of \begin{document}$ \Xi_c\to\Xi $\end{document} that can be further applied to relevant estimates. In this study, we used the light-front quark model to carry out computations where the three-body vertex functions for \begin{document}$ \Xi_c $\end{document} and \begin{document}$ \Xi $\end{document} are employed. To fit the new data of the Belle II, we re-adjusted the model parameters to obtain \begin{document}$ \beta_{s[sq]} = 1.07 $\end{document} GeV, which is 2.9 times larger than \begin{document}$ \beta_{s\bar s} = 0.366 $\end{document} GeV. This value may imply that the \begin{document}$ ss $\end{document} pair in \begin{document}$ \Xi $\end{document} constitutes a more compact subsystem. Furthermore, we investigated the non-leptonic decays of \begin{document}$ \Xi^{(')}_c\to \Xi $\end{document}, which will be experimentally measured soon. Thus, our model will be tested in terms of consistency with the new data."> Weak decays of <inline-formula><tex-math id="M1-5">\begin{document}${\boldsymbol \Xi^{(')}_{\boldsymbol c}\to \boldsymbol\Xi }$\end{document}</tex-math><alternatives><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/834586a8-05ad-43cf-9619-430ba8fe06ed/CPC-2021-0303_M1-5.jpg"/><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/834586a8-05ad-43cf-9619-430ba8fe06ed/CPC-2021-0303_M1-5.png"/></alternatives></inline-formula> in the light-front quark model -
