Interference and binding effects in decays of possible molecular component of X (3872)

It is pointed out that the internal structure of the narrow resonance X(3872) at the D-0(D) over bar*(0) threshold can be studied in some detail by measuring the rate and the spectra in the decays X(3872) --> D-0(D) over bar (0)pi(0) and X(3872) --> D-0(D) over bar (0)gamma. In particular, if this resonance contains a dominant molecular component D(D) over bar* +/- (D) over barD*, this component can be revealed and studied by a distinct pattern of interference between the underlying decays of D*(0) and (D) over bar*(0) whose coherence is ensured by fixed (but yet unknown) C parity of the X(3872).
