We review the current status of heavy-quark symmetry and its applications to weak decays of
hadrons containing a single heavy quark. After an introduction to the underlying physical …

The approximate symmetries of Quantum ChromoDynamics in the infinite heavy quark (Q=
c, b) mass limit (mQ→∞) and in the chiral limit for the light quarks (mq→ 0, q= u, d, s) can be …

In an analysis of a 2.92 fb-1 data sample taken at 3.773 GeV with the BESIII detector
operated at the BEPCII collider, we measure the absolute decay branching fractions B (D …

We study the decay constants and form factors of the ground-state s-wave and low-lying p-
wave mesons within a covariant light-front approach. Numerical results of the form factors for …

We calculate the form factors for weak decays of B (s) and D (s) mesons to light
pseudoscalar and vector mesons. To reveal the intimate connection between different decay …

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 calculate the D* Dπ and B* Bπ couplings using QCD sum rules on the light cone. In this
approach, the large-distance dynamics is incorporated in a set of pion wave functions. We …

We present a systematic study of twist-3 and twist-4 light-cone distribution amplitudes of the
K meson in QCD. The structure of SU (3)-breaking corrections is studied in detail. Non …

The authors review the experimental measurements and theoretical descriptions of leptonic
and semileptonic decays of particles containing a single heavy quark, either charm or …

Within the light-front framework, form factors for P→ P and P→ V transitions (P denotes a
pseudoscalar meson, V a vector meson) due to the valence-quark configuration are …
