D_s(0^±) Meson Spectroscopy in Gaussian Sum Rules

Masses of the D_s(0^±)mesons are investigated from a view-point of ordinary light-heavy system in the framework of the Gaussian sum rules, which are worked out by means of the Laplacian transformation to the usual Borel sum rules. Using the standard input of QCD non-perturbative parameters, the corresponding mass spectra and couplings of the currents to the D_s(0^±) mesons are obtained. Our results are m_Ds(0^-)=1.968±0.016±0.003GeV and m_Ds(0⁺)=2.320±0.014±0.003GeV, which are in good accordance with the experimental data, 1.969GeV and 2.317GeV.
