摘要：

The interaction between pseudoscalar and/or vector mesons can be studied using hidden gauge Lagrangians. In this framework, the interaction between charmed mesons has been studied. Furthermore, doubly charmed states are also predicted. These new states are near the D* D* and D* D-s* thresholds, and have spin-parity J(P) = 1(+). We evaluate the decay widths of these states, named as R-cc(3970) and S-cc(4100) (with strangeness), and obtain 44 MeV for the non-strangeness, and 24 MeV for the doubly charm-strange state. Essentially, the decay modes are DD(s)pi and DD(s)gamma, being the D pi and D gamma emitted by one of the D* meson which forms the molecule.
