Abstract

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 0103-9733.  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.

Keywords : Charmed scalar mesons; QCD Sum Rules.
