Abstract

Without contamination from the final state interactions, the calculation of the branching ratios of semileptonic decays may provide further information about the inner structure of charmed baryons. Moreover, by studying such processes, one can better determine the form factors of 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 and are employed. To fit the new data of the Belle II, we re-adjusted the model parameters to obtain GeV, which is 2.9 times larger than GeV. This value may imply that the pair in constitutes a more compact subsystem. Furthermore, we investigated the non-leptonic decays of , which will be experimentally measured soon. Thus, our model will be tested in terms of consistency with the new data.
