Abstract: (arXiv)

The X(3872) resonance is considered as a hadronic molecule, a loosely-bound state of charmed D0 and D*0 mesons, since its mass is very close to the D*0 barD0 threshold. Assuming structure and quantum numbers of X(3872) as (D0 barD*0 - D*0 barD0)/sqrt(2) and J(PC) = 1(++), we calculate the X(3872) to gamma J/psi decay using a phenomenological Lagrangian approach.
