Abstract
We investigate the two-body nonleptonic weak decays of Λb baryon into a Λc baryon and a pseudoscalar or vector meson in the framework of HQET. With the additional assumption of factorization the branching ratios and asymmetry parameters for various decay processes [Formula: see text] are obtained. Treating the s quark as heavy we have also applied HQET to study the decay process Λb→ΛJ/ψ and the estimated branching ratio for this process is lying within the present experimental limits.
