Radiative Corrections to Radiative B Decays: Exclusive B -> V gamma at NLO
Gerhard Buchalla
We discuss a model-independent framework for the analysis of the radiative B-meson decays B -> K* gamma and B -> rho gamma based on the heavy-quark limit of QCD. We present a facto…
The Double Radiative Decays in the Heavy Quark Limit
Stefan W. Bosch, Gerhard Buchalla
We analyze the double radiative B-meson decays B_s -> gamma gamma and B_d -> gamma gamma in QCD factorization based on the heavy-quark limit m_b >> Lambda_QCD. We systematically di…
The B^+ B_d^0 Lifetime Difference Beyond Leading Logarithms
M. Beneke, G. Buchalla, C. Greub +2
We compute perturbative QCD corrections to the lifetime splitting between the charged and neutral meson in the framework of the heavy quark expansion. These next-to-leading log…
Heavy Quark Theory
Gerhard Buchalla
These lectures describe the most important theoretical methods in b-physics. We discuss the formalism of effective weak Hamiltonians, heavy quark effective theory, the heavy quark…
