Abstract
In this paper, we assign the newly reported state [Formula: see text] to be a [Formula: see text]-wave [Formula: see text] meson, and study its mass and decay constant with QCD sum rules by considering the contributions of vacuum condensates up to dimension-6 in the operator product expansion. The predicted mass [Formula: see text] GeV is in agreement with the experimental data [Formula: see text] MeV from the LHCb collaboration. This result supports assigning [Formula: see text] as the [Formula: see text] charmonium meson. In this case, its predicted strong decay width with the [Formula: see text] decay model is compatible with the experimental data.
