Exclusive Semi-Leptonic Decays of b-Baryons into Protons
Will Loinaz, R. Akhoury
Abstract
We present a QCD-based calculation of the exclusive semileptonic decay Lambdab -> p l nu-bar. Using the ideas of Heavy Quark Effective Theory, we discuss the factorization of the amplitude. Further, resummed Sudakov effects are put in to ensure a consistent perturbative expansion.
