====== TTP99-31 QCD-Based Description of One-Particle Inclusive B-Decays ====== We discuss one-particle inclusive B decays in the limit of heavy b and c quarks. Using the large-N_C limit we factorize the non-leptonic matrix elements, and we employ a short distance expansion. Modeling the remaining nonperturbative matrix elements we obtain predictions for various decay channels and compare them with existing data. |**Xavier Calmet, Thomas Mannel and Ingo Schwarze** | |** Phys.
