Abstract

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