Abstract

We discuss the possible interpretation of X(3872) as a DD* hadronic molecule with J^PC = 2^-+. Using the phenomenological Lagrangian approach, we studied its radiative and strong decay properties. We find that our model with about 97.6% isospin zero component explains the existing data nicely. We predict the partial widths of the radiative and strong decays of X(3872) and show that the measurement of the ratio may signal the nature of X(3872).
