Inclusive semi-leptonic B decays to order 1/mb4
- 1. Theoretische Physik 1, Fachbereich Physik, Universitaet Siegen, D-57068 Siegen (Germany)
Description
We give a systematic way to compute higher orders in the 1/mb expansion in inclusive semi-leptonic decays at tree-level. We reproduce the known 1/mb3 terms and compute the 1/mb4 terms at tree-level. The appearing non-perturbative parameters and the impact on the determination of Vcb are discussed
