The property of X(3872) particle is discussed by carefully studying the experimental data available. We find that two poles near the D *0 D̄ 0 threshold are required in order to describe the data better. The stability of the pole locations is further tested by varying fit methods and it is found that our qualitative result is unchanged. We conclude that the X(3872) particle is a c̄c state heavily distorted by the D *0 D̄ 0 threshold. © 2010 American Institute of Physics.
