On the structure of X(3872) particle.

The property of X(3872) particle is discussed by carefully studying the experimental data available. We find that two poles near the D*0D0 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 cc state heavily distorted by the D*0D0 threshold. [ABSTRACT FROM AUTHOR]
