| contents | We analyze the recent data from the BESIII collaboration on the $X(3872)$ state in the $J/ψπ^+π^-$ and $D^0\bar{D}^0π^0$ decay channels. The quantum number and mass of the $X(3872)$ state allow us to exploit the universal feature of the very near-threshold $D\bar D^*$ scattering in the $S$ wave. The analysis of $J/ψπ^+π^-$ data and $D^0\bar{D}^0π^0$ data separately as well as the combined analysis of these data together, all support the conclusion that $X(3872)$ is an extremely weakly bound charm meson molecule. |
