Nature of X(3872) from recent BESIII data: Considering the universal feature of an S-wave threshold resonance

Xian-Wei Kang, Jin-Zhe Zhang, Xin-Heng Guo

We analyze the recent data from the BESIII collaboration on the $X(3872)$ state in the $J/\ddot{I}ˆ\ddot{I}{€}^{+}\ddot{I}{€}^{-}$ and $D^0{\bar{D}}^0\ddot{I}{€}^0$ decay channels. The quantum number and mass of the $X(3…
