Description
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 doubly charmed meson molecules into DD_{(s)}\gamma. Essentially, the decay modes are three body DD_{(s)}\pi and DD_{(s)}\gamma decays, with the D\pi and D_{(s)}\gamma emitted by one of the D^*_{(s)} meson which forms the molecule. In addition, we consider the possible coupled channel system DD^*-D^*D^*. These new states could be observed in experimental facilities as the LHCb.
