Effective Field Theory and Heavy Quark Physics
Matthias Neubert
These notes are based on five lectures presented at the 2004 Theoretical Advanced Study Institute (TASI) on ``Physics in D>=4''. After a brief motivation of flavor physics, they pr…
Toward a NNLO calculation of the B-->X_s gamma decay rate with a cut on photon energy: I. Two-loop result for the soft function
Thomas Becher, Matthias Neubert
A theoretical analysis of the partial inclusive B-->X_s gamma decay rate with a cut E_gamma>E_0 on photon energy must deal with short-distance contributions associated with three d…
Model-Independent Properties of the B-Meson Distribution Amplitude
Seung J. Lee, Matthias Neubert
The operator product expansion is used to obtain model-independent predictions for the first two moments of the renormalized B-meson light-cone distribution amplitude phi_+(omega,m…
A two-loop relation between inclusive radiative and semileptonic B-decay spectra
Bjorn O. Lange, Matthias Neubert, Gil Paz
A shape-function independent relation is derived between the partial B->X_u+l+nu decay rate with a cut on P_+=E_X-P_X<Delta and a weighted integral over the normalized B->X_s+gamma…
Advanced Predictions for Moments of the B->X_s+gamma Photon Spectrum
Matthias Neubert
Based on a new, exact QCD factorization formula for the partial B->X_s+gamma decay rate with a restriction on large photon energy, improved predictions are presented for the partia…
The Discovery Potential of a Super B Factory
JoAnne. L. Hewett, David G. Hitlin, T. Abe +96
The Proceedings of the 2003 SLAC Workshops on flavor physics with a high luminosity asymmetric e+e- collider. The sensitivity of flavor physics to physics beyond the Standard Model…
Theory of Charmless Inclusive B Decays and the Extraction of V_{ub}
Bjorn O. Lange, Matthias Neubert, Gil Paz
We present ``state-of-the-art'' theoretical expressions for the triple differential B->X_u l^- nu decay rate and for the B->X_s gamma photon spectrum, which incorporate all known c…
Factorization in B->V gamma Decays
Thomas Becher, Richard J. Hill, Matthias Neubert
The factorization properties of the radiative decays B->V gamma are analyzed at leading order in 1/m_b using the soft-collinear effective theory. It is shown that the decay amplitu…
