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

Motivated by the success of the flavour physics programme carried out over the last decade
at the Large Hadron Collider (LHC), we characterize in detail the physics potential of its High …

We review weakly-bound heavy quarkonium systems using effective field theories of QCD.
We concentrate on potential non-relativistic QCD, which provides with a well founded …

Recently there has been interest in the correlation between R (D*) and the branching ratio
(BR) of B c-→ τ ν¯ in models with a charged scalar H±. Any enhancement of R (D*) by …

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 …

Semileptonic and nonleptonic decays of the B c meson to charmonium and D mesons are
studied in the framework of the relativistic quark model. The decay form factors are explicitly …

The form factors parametrizing the B c semileptonic matrix elements can be related to a few
invariant functions if the decoupling of the spin of the heavy quarks in B c and in the mesons …

In the framework of three-point QCD sum rules, the form factors for the semileptonic decays
of B c+→ B s (B s∗) l+ ν l are calculated with account for the Coulomb-like αs/v-corrections in …

A bstract The first observation of the\({B} _c^{+}\to J/\psi {\pi}^{+}{\pi}^ 0\) decay is reported
with high significance using proton-proton collision data, corresponding to an integrated …

We study the semileptonic decays of the B c meson into final charmonium states within the
standard model and beyond. The relevant hadronic transition form factors are calculated in …
