• D-s3*(2860)
• QCD sum rules

In this article, we assign the D-s3* (2860) to be a D-wave cs meson, and study the mass and decay constant of the D-s3* (2860) with the QCD sum rules by calculating the contributions of the vacuum condensates up to dimension-6 in the operator product expansion. The predicted mass M-Ds3* = (2.86 0.10) GeV is in excellent agreement with the experimental value M-Ds3* = (2860.5 +/- 2.6 +/- 2.5 +/- 6.0) MeV from the LHCb collaboration. The present prediction supports assigning the Vs'3 (2860) to be the D-wave c (s) over bar meson.
