Diquark-Antidiquark with open charm in QCD sum rules
Using the QCD sum rule approach we investigate the possible four-quark structure of the recently observed charmed scalar mesons D 0(2308) (BELLE) and D 0,+ 0 (2405) (FOCUS) and also of the very narrow D sJ (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 fourquark structu...
متن کاملCharm and bottom quark masses from QCD moment sum rules
In this work the charm and bottom quark masses are determined from QCD moment sum rules for the charmonium and upsilon systems. In our analysis we include both the results from non-relativistic QCD and perturbation theory at next-next-to-leading order. For the pole masses we obtain Mc = 1.75± 0.15 GeV and Mb = 4.98± 0.125 GeV. Using the potential-subtracted mass in intermediate steps of the cal...
متن کاملMultiquark states and QCD sum rules
There have been arguments about hadronic molecules, which are weakly-bound states of two or more hadrons. We investigate the possibility of some candidates (f0(980), a0(980), f0(1500), f0(1710), etc.) using QCD sum rule approach and compare our results with multiquark states in the MIT bag model. We find that f0(1500), f0(1710) can be good candidates for vector-vector molecule-type multiquark s...
متن کاملMass of the charm-quark from QCD sum rules
Relativistic and non-relativistic ratios of Laplace transform QCD moment sum rules for charmonium are used in order to determine the value of the on-shell charmquark mass. The validity of the non-relativistic version of QCD sum rules in this particular application is discussed. After using current values of the perturbative and non-perturbative QCD parameters, as well as experimental data on th...
متن کاملCharm-quark mass from weighted finite energy QCD sum rules
The running charm-quark mass in the MS scheme is determined from weighted finite energy QCD sum rules (FESR) involving the vector current correlator. Only the short distance expansion of this correlator is used, together with integration kernels (weights) involving positive powers of s, the squared energy. The optimal kernels are found to be a simple pinched kernel, and polynomials of the Legen...
