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.
