In this work, we evaluate the D+ sJ(2317), D 0 0(2308), D 0 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. The detailed study of charmed scalar meson spectroscopy has provided many informations about the properties of q ¯ c systems. However, our knowledge is still not enough to un- derstand all the meson states known nowadays. In 1977, R. L. Jaffe proposed a diquark (qq) antidiquark (¯ q ¯
