▪ 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 current literature. Among other topics we discuss (a) basic parameters of the heavy-quark theory; (b) a class of exact QCD inequalities; (c) new heavy quark sum rules; (d) the virial theorem; (e) applications (|Vcb| from the total semileptonic width and from the B → D* transition at zero recoil). In some…

A few aspects of heavy quark expansion
Two topics in heavy quark expansion are discussed. The heavy quark potential in perturbation theory is reviewed in connection to the problem of the heavy quark mass. The non-trivial reason behind the
Applications of heavy quark methods
For the computation of processes in the Standard Model of Elementary Particle Physics (SM), so-called effective field theories (EFTs) are used. In this way, it is possible to treat corrections
HEAVY QUARKS ON THE LATTICE
▪ Abstract Lattice quantum chromodynamics provides first-principles calculations for hadrons containing heavy quarks—charm and bottom quarks. Their mass spectra, decay rates, and some hadronic matrix
Precision studies of duality in the ’t Hooft model
The authors address numerical aspects of local quark-hadron duality using the example of the exactly solvable 't Hooft model, two-dimensional QCD with Nc ?8. The primary focus of these studies is
Heavy Quark Theory
These lectures describe the most important theoretical methods in b-physics. We discuss the formalism of eective weak Hamiltonians, heavy quark eective theory, the heavy quark expansion for inclusive
B → D* zero-recoil formfactor and the heavy quark expansion in QCD: a systematic study
A bstractWe present a QCD analysis of heavy quark mesons focussing on the B → D* formfactor at zero recoil, FD* (1). An advanced treatment of the perturbative corrections in the Wilsonian approach is
Soft-Collinear Factorization and Sudakov Resummation of Heavy Meson Decay Amplitudes with Effective Field Theories
In this thesis we present an introduction to Soft-Collinear Effective Theory, which can be used to prove (or disprove) factorization theorems to all orders in the strong coupling constant for some B
Non-perturbative tests of continuum HQET through small-volume two-flavour QCD
A bstractWe study the heavy quark mass dependence of selected observables constructed from heavy-light meson correlation functions in small-volume two-flavour lattice QCD after taking the continuum

ON THE MOTION OF HEAVY QUARKS INSIDE HADRONS: UNIVERSAL DISTRIBUTIONS AND INCLUSIVE DECAYS
In previous papers we have pointed out that there exists a QCD analog of the phenomenological concept of the so-called Fermi motion for the heavy quark inside a hadron. Here we show in a more
Operator product expansion, heavy quarks, QCD duality and its violations
The quark(gluon)–hadron duality constitutes a basis for the theoretical treatment of a wide range of inclusive processes — from hadronic τ decays and Re+e- to semileptonic and nonleptonic decay rates
Ds lifetime,mb,mc and |Vcb| in the heavy quark expansion
We present some straightforward applications of the QCD heavy quark expansion, stated in previous papers [1–3], to the inclusive widths of heavy flavour hadrons. We address the question of theDs
How to Measure Kinetic Energy of the Heavy Quark Inside B Mesons
We discuss how one can determine the average kinetic energy of the heavy quark inside heavy mesons from differential distributions in B decays. A new, so-called third, sum rule for the b → c
