The form factors of the 
decay are calculated in the framework of the light cone QCD sum rules. In the calculations the contribution of the negative parity 
baryon is eliminated by constructing the sum rules for different Lorentz structures. Furthermore the branching ratio of the semileptonic 
decay is calculated. The numerical study for the branching ratio of the decay indicates that it is quite large and could be measurable at future planned experiments to be conducted at LHCb.
