In this work, we analyze the semileptonic decay processes of in the light-cone sum rule approach. In order to calculate the form factors of the baryon transition matrix element, we use the light-cone distribution amplitudes of obtained from the QCD sum rule in the heavy quark effective field theory framework. With the calculation of the six form factors of the transition matrix element, the differential decay widths of and their absolute branching fractions are obtained. Additionally, the ratio of is also obtained in this work. Our results are in accord with the newest experimental result and other theoretical calculations and predictions.
