AB  - In this work we use an effective field theory (EFT) approach to study the X(3872) resonance, assuming a heavy meson-heavy antimeson molecule as itsinner structure. From this EFT we extract some direct consequences for the hidden charm and bottom hadronic spectrum.Within this EFT we also study the decay X(3872) → D<sup>0</sup>―D<sup>0</sup> π<sup>0</sup>. This decay is unique since it is more sensitive to the long-distance part of the X(3872) wave function than the X(3872)→ J/ψππ and X(3872)→ J/ψπππ modes. We also show that the possible D―D Final State Interactions (FSI) effects can lead to experimental constrains on the Low Energy Constants (LECs) that appear in the EFT and the possible existence of a loosely D―D bound state.
