Study of two-body hadronic decays of Lambda(b) baryon in the heavy quark effective theory

We investigate the two-body nonleptonic weak decays of Lambda(b) baryon int o a Lambda(c) 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 Lambda(b) --> Lambda( c)(+)P(-)(V-) are obtained. Treating the s quark as heavy we have also appl ied HQET to study the decay process Lambda(b) --> Lambda J/psi and the esti mated branching ratio for this process is lying within the present experime ntal limits.
