Subleading Shape Functions in Inclusive B Decays
Stefan W. Bosch, Matthias Neubert, Gil Paz
The contributions of subleading shape functions to inclusive decay distributions of B mesons are derived from a systematic two-step matching of QCD current correlators onto soft-co…
Proposal for a Precision Measurement of |Vub|
Stefan W. Bosch, Bjorn O. Lange, Matthias Neubert +1
A new method for a precision measurement of the CKM matrix element |Vub| is discussed, which combines good theoretical control with high efficiency and a powerful discrimination ag…
Factorization and Shape-Function Effects in Inclusive B-Meson Decays
S. W. Bosch, B. O. Lange, M. Neubert +1
Using methods of effective field theory, factorized expressions for arbitrary B -> X_u l nu decay distributions in the shape-function region of large hadronic energy and moderate h…
