LOZEA, A.; BRACCO, M. E.; MATHEUS, R. D. and NIELSEN, M.. Charmed scalar mesons masses within the QCD sum rules framework. Braz. J. Phys. [online]. 2007, vol.37, n.1a, pp. 67-70. ISSN 1678-4448. http://dx.doi.org/10.1590/S0103-97332007000100021.
In this work, we evaluate the D+sJ(2317), D00(2308), D00(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.
