Properties of X(3872) are studied by regarding it as a DDβ hadronic
molecule with JPC=2β+ in the phenomenological Lagrangian approach. We
find that our model with about 97.6% isospin zero component explains the
existing data nicely, for example, the ratio B(X(3872)βJ/ΟΟ+ΟβΟ0)/B(X(3872)βJ/ΟΟ+Οβ). We predict
the partial widths of the radiative decays of X(3872)βΞ³J/Ο,
Ξ³Ο(2S) and the strong decays of X(3872)βJ/ΟΟ+Οβ,
J/ΟΟ+ΟβΟ0 as well as X(3872)βΟcJβΟ0. Our analysis
shows that the measurement of the ratio B(X(3872)βΟc0βΟ0)/B(X(3872)βΟc1βΟ0) may signal the nature
of X(3872)
