Abstract

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