Abstract

In this article, we use the light-cone QCD sum rules to relate the Λ_b baryon light-cone distribution amplitudes to the Isgur-Wise function ξ(ω) of the Λ_b → Λ_c transition, and obtain a simple relation. The numerical value of the Isgur-Wise function ξ(ω) is consistent with the prediction of the QCD sum rules.
