- Resumo: In this talk I present a study of the D ∗ρ system made by using the method of QCD sum rules. Considering isospin and spin projectors, we investigate the different configurations and obtain three D ∗ mesons with isospin I = 1/2, spin S = 0, 1, 2 and with masses 2500 ± 67 MeV, 2523 ± 60 MeV, and 2439 ± 119 MeV, respectively. The last state can be related to D ∗ 2 (2460) (spin 2) listed by the Particle Data Group, while one of the first two might be associated with D ∗ (2640), whose spin-parity is unknown. In the case of I = 3/2 we also find evidences of three states with spin 0, 1 and 2, respectively, with masses 2467±82 MeV, 2420±128 MeV, and 2550±56 MeV.
