Abstract It is pointed out that the internal structure of the narrow resonance X(3872) at the D 0 D ∗0 threshold can be studied in some detail by measuring the rate and the spectra in the decays X(3872)→D 0 D 0 π 0 and X(3872)→D 0 D 0 γ . In particular, if this resonance contains a dominant “molecular” component D D ∗ ± D D ∗ , this component can be revealed and studied by a distinct pattern of interference between the underlying decays of D ∗0 and D ∗0 whose coherence is ensured by fixed (but yet unknown) C parity of the X(3872).

• Universality in few‐body systems with large scattering length (2004, background): “If the X(3872) is indeed a D0D̄∗0/D̄0D∗0 molecule, then it has universal properties that are determined by the unnaturally large scattering length [35,36].”
• Hadronic molecules (2017, background): “…following four states: 1−−` ⊗ 0−+cc̄ = 1+−, 1−−` ⊗ 1−−cc̄ = 0++ ⊕ 1++ ⊕ 2++. (77) It becomes clear that if the 1++ state X(3872) is a DD̄∗ molecule, then it is in the multiplet with j` = 1 (Voloshin, 2004a), and has three spin partners with JPC = 0++, 2++ and 1+− in the strict heavy quark limit…”
• The Exotic XYZ Charmonium-Like Mesons (2008, background): “In this molecular scenario, the decays of the X(3872) into D∗0D̄0π0 and D∗D̄0γ proceed through the decays of its constituent D∗0 with branching ratios similar to those of the D∗0 (72, 69).”
