摘要：
We study the exclusive flavor changing neutral current process Lambda b -> Lambda nu(nu) over bar in the leptophobic Z' model, where charged leptons do not couple to the extra Z' boson. The branching ratio, as well as, the longitudinal, transversal and normal polarizations are calculated. It has been shown that all these physical observables are very sensitive to the existence of new physics beyond the standard model and their experimental measurements can give valuable information about it.
