Several observed states close to the D\bar{D}^* and D^*_{(s)}\bar{D}^*_{(s)} thresholds, as the X(3872) and some XYZ particles can be described in terms of a two-meson molecule. Furthermore, doubly charmed states are also predicted, named as R_{cc}(3970) and S_{cc}(4100). These new states are near the DD^*, D^*D^* and D^*D^*_s thresholds. We compute decays into DD\pi and radiative decays of...

Hadron as an impurity bound in nuclei causes interesting phenomena which
do not emerge in normal nuclei.
These effects would give us the information not only on the internal
structure of the nuclei, but also on the changing properties of the
impurity in the nuclear medium.
The hadron-nucleus systems have been studied in the light flavor
sector, especially.
However, a strong...

We study possible baryon molecules in the non-strange heavy baryon spectrum.
We include configurations with a heavy-meson and a light baryon. We find
several structures, in particular we can understand the $\Lambda_c(2940)$
as a $D^{\ast} N$ molecule with $J^P=3/2^-$ quantum numbers. We also find
$D^{(\ast)} \Delta$ candidates for the recently discovered $X_c(3250)$ and
$X_c(3212)$ resonances.

Recently, many candidate multiquark mesons, i.e., mesons with substructures that are more complex that the quark-antiquark prescription that is in the textbooks, have been observed. Many of the most recently observed candidate states are electrically charged and have the same spin and parity, namely JP=1+. In this talk I will give an overview of the current experimental situation and try to...
