Abstract
The two body non-leptonic Λb decays are analyzed in the HQET with factorization approximation and large Nc limit. In this limit, Λb and Λc baryons can be treated as the bound states of chiral soliton and heavy meson, and consequently the Isgur-Wise function comes out in a straight forward manner. The results obtained remain well below their previously predicted upper limit.
