We investigate the decay of Λb→Λνν̄ with the polarized baryons of Λb and Λ. With the most general hadronic form factors, we first study the decay branching ratio and then derive the longitudinal, normal, and transverse polarizations of Λ in terms of the spin unit vectors of Λb and A Λ the momentum of Λ. A polarization of Λb is also discussed.
