Hadronic structure - reactions, production and decays
Oral presentation
We present a short review of the theoretical and experimental status of
$X(3872)$ production in high energy proton-proton and nucleus-nucleus
collisions at the LHC. We then discuss the interaction of the $X(3872)$
with light mesons in a hadron gas.

Hadronic structure - reactions, production and decays
Oral presentation
We calculate the branching ratio for the production of the meson $Y(4260)$ in the decay $B^- \to Y(4260)K^-$. We use QCD sum rules approach and we consider the $Y(4260)$ to be a mixture between charmonium and exotic tetraquark, $[\bar{c}\bar{q}][qc]$, states with $J^{PC}=1^{--}$. Using the value of the mixing angle determined previously as: $\theta=(53.0\pm0.5)^\circ$, we get the branching...

Hadronic structure - reactions, production and decays
Oral presentation
We perform a field-theoretical study of possible deuteron-like molecules with
both open charm and bottom, using the Heavy-Meson Effective Theory. In
this approach, we analyze the parameter space of the coupling constants and discuss the
formation of loosely-bound $D^{(*)} B^{(*)} $-states. We estimate
their masses and other properties.

Hadronic structure - reactions, production and decays
Oral presentation
In this study, we investigate the electromagnetic form factors, $F^{em}_{X^{0^-}}$, decay constants, $f_{X^{0^-}}$, and charge radii, $\langle r_{X^{0^-}}\rangle$, where $X^{0^-}=\pi^+\text{ or }K^+$, for pion and kaon within the frame work of light-front field theory formalism using symmetric vertex function as a quark-meson interaction vertex. The above mentioned observables are evaluated...

Hadronic structure - reactions, production and decays
Oral presentation
One of the challenges of the modern physics
is the description of the internal structure
of the baryons and mesons.
The electromagnetic structure
of the nucleon $N$ and the nucleon resonances $N^\ast$ can be accessed
through the $\gamma^\ast N \to N^\ast$ reactions,
which deppend of the (photon) transfer momentum squared $Q^2$ [1--4].
The data associated with those transitions...
