Abstract

We discuss the possibility that the X(3872) can be a DD^* molecular bound state in the Bethe-Salpeter equation approach in the ladder and instantaneous approximations. We show that the DD^* bound state with quantum numbers J^PC=1⁺⁺ exists. We also calculate the decay width of X(3872)\ensuremath→\ensuremathγJ/\ensuremathψ channel and compare our result with those from previous calculations.
