We review the present status of QCD corrections to weak decays beyond the leading-
logarithmic approximation, including particle-antiparticle mixing and rare and CP-violating …

Experimental and theoretical studies of CP violation in the B s 0 system are reviewed.
Updated predictions for the mixing parameters of the B s 0 mesons expected in the standard …

A bstract We present a considerably improved analysis of model-independent bounds on
new physics effects in non-leptonic tree-level decays of B-mesons. Our main finding is that …

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 …

▪ 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 …

A bstract We provide an extensive study of the lifetimes of singly charmed baryons and
mesons, within the heavy quark expansion with all known corrections included. A special …

Theoretical predictions for B decay rates are rewritten in terms of the Υ (1 S) meson mass
instead of the b quark mass, using a modified perturbation expansion. The theoretical …

Basic physical characteristics of doubly heavy baryons are examined, including
spectroscopy (which is treated in the potential approach and within the QCD sum rules …

We present a model-independent study of spectator effects, which are responsible for the
lifetime differences between beauty hadrons. These effects can be parametrized in terms of …

A bstract Applying an operator product expansion approach we update the Standard Model
prediction of the B c lifetime from over 20 years ago. The non-perturbative velocity …
