Description
Using the QCD sum rule approach we investigate the possible four-quark structure of the recently observed charmed scalar mesons D00(2308) (BELLE) and D00,+(2405) (FOCUS) and also of the very narrow DsJ+(2317), firstly observed by BABAR. We use diquak-antidiquark currents and work to the order of ms in full QCD, without relying on 1/mc expansion. Our results indicate that a four-quark structure is acceptable for the resonances observed by BELLE and BABAR: D00(2308) and DsJ+(2317) respectively, but not for the resonances observed by FOCUS: D00,+(2405)
