▪ Abstract Recent achievements in heavy-quark theory are critically reviewed. The emphasis
is put on those aspects that either did not attract enough attention or cause heated debates …

In the past decade, one of the major challenges of particle physics has been to gain an in-
depth understanding of the role of quark flavor. In this time frame, measurements and the …

The inspiration for this book came from François le Diberder. During his term as
spokesperson for B 八 B 八 R he laid down a vision for the two B Factory detector …

A bstract We present an ab initio study of inclusive semileptonic decays of heavy mesons
from lattice QCD. Our approach is based on a recently proposed method, that allows one to …

A bstract We compute the first moments of the q 2 distribution in inclusive semileptonic B
decays as functions of the lower cut on q 2, confirming a number of results given in the …

We postulate a supplemental power counting within the heavy quark effective theory (HQET)
that results in a small, highly constrained set of second-order power corrections, compared …

We compute corrections of order α s 3 to the decay b→ c ℓ ν¯ taking into account massive
charm quarks. In the on-shell scheme large three-loop corrections are found. However, in …

We develop a method to compute the inclusive semileptonic decay rate of hadrons fully
nonperturbatively using lattice QCD simulations. The sum over all possible final states is …

We extract the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element V cb and the
most relevant parameters of the heavy quark expansion from data of inclusive semileptonic …

One of the most troublesome contributions to the NNLO QCD corrections to B¯→ Xsγ
originates from three-loop matrix elements of four-quark operators. A part of this contribution …
