Analysis of the (3842) as a -wave charmonium meson
Abstract
In this paper, we assign the newly reported state to be a -wave 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 GeV is in agreement with the experimental data MeV from the LHCb collaboration. This result supports assigning as the charmonium meson. In this case, its predicted strong decay width with the decay model is compatible with the experimental data.
