Λ{sub}b decay to Λ and η'

摘要

The two-body hadrcmic decay ofΛ{sub}b baryon to A + η'is investigated. We estimate the nonfactorizable contribution due to the gluon fusion mechanism which could be the possible dominant process in η' production in hadronic B decays. Our crude estimate, which is made by factorizing weak and strong vertices, point to a significant enhancement of the branching ratio due to the gluon fusion mechanism in this baryonic decay.
