Most inclusive rare B decays are important modes of flavor physics due to the small hadronic
uncertainties. In this article, the author gives a status report on such decays, highlighting …

We calculate the long-distance effect generated by the four-quark operators with c-quarks in
the B→ K (*) ℓ+ ℓ− decays. At the lepton-pair invariant masses far below the\(\bar {c} c\) …

Combining our results for various O (α s 2) corrections to the weak radiative B-meson decay,
we are able to present the first estimate of the branching ratio at the next-to-next-to-leading …

These lectures describe in detail the effective Hamiltonians for weak decays of mesons
constructed by means of the operator product expansion and the renormalization group …

Using a theoretical framework based on the next-to-leading-order QCD-improved effective
Hamiltonian and a factorization ansatz for the hadronic matrix elements of the four-quark …

The rare decays B 0→ K* 0 μ+ μ-and B s→ ϕ μ+ μ-are now being observed with enough
precision to test Standard Model predictions. A full understanding of these decays requires …

An introduction to the method of QCD sum rules is given for those who want to learn how to
use this method. Furthermore, we discuss various applications of sum rules, from the …

We present the QCD corrections to the matching conditions of the ΔB= 1 magnetic and
chromo-magnetic operators in the Standard Model and in two-Higgs doublet models. We …

The charm-loop contribution to B ̄→ X sγ is found to be numerically dominant and very
stable under logarithmic QCD corrections. The strong enhancement of the branching ratio by …

We present an updated next-to-leading order analysis of the B→X_sγ branching ratio and
photon spectrum, including consistently the effects of Fermi motion in the heavy-quark …
