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 …

B mesons are bound states of ab quark and a light anti-quark. While the binding is provided
by the strong interaction B mesons can only decay by the weak interaction. Since the top …

We review the experimental and theoretical status of baryons containing one heavy quark.
The charm and bottom baryon states are classified and their mass spectra are listed. The …

We investigate the structure of heavy baryons containing a charm or a bottom quark. We
employ a constituent quark model successful in the description of the baryon–baryon …

We discuss the production via fragmentation of excited heavy mesons and baryons, and
their subsequent decay. In particular, we consider the question of whether a net polarization …

Cabibbo-allowed two-body hadronic weak decays of bottom baryons are analyzed. Contrary
to the charmed baryon sector, many channels of bottom baryon decays proceed only …

Weak current-induced baryonic form factors at zero recoil are evaluated in the rest frame of
the heavy parent baryon using the nonrelativistic quark model. Contrary to previous similar …

Exclusive nonleptonic decays of bottom and charm baryons are studied within a relativistic
three-quark model with a Gaussian shape for the momentum dependence of the baryon …

A bstract In the 1990s, very low experimental values for the lifetime ratio τ (Λ b)/τ (B d)
triggered a considerable amount of doubt in the applicability of the heavy quark expansion …

We present the results of a comprehensive analysis of the angular decay distributions
occurring in the weak exclusive decays of the lowest lying charm and bottom mesons and …
