Abstract

The masses of the Ds(0±)D_s(0^\pm) 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 Ds(0±)D_s(0^\pm) mesons are obtained. Our results are mDs(0)=1.968±0.016±0.003m_{D_s(0^-)}=1.968\pm0.016\pm0.003 GeV and mDs(0+)=2.320±0.014±0.003m_{D_s(0^+)}=2.320\pm0.014\pm0.003 GeV, which are in accordance well with the experimental data, 1.969 GeV and 2.317 GeV.
