| English abstract | In this work, we evaluate the D+ sJ (2317), D0 0(2308), D0 0(2407) and D+ 0 (2403) masses. These are scalar mesons recently discovered in the BABAR, BELLE and FOCUS Collaborations. The nature of these particles is intensely discussed nowadays. We treat them as a diquark-antidiquark configuration and treat the problem using the QCD sum rules (QCDSR) approach |
