Abstract：
The spin is an important property of a particle. Although it is unlikely, there is still a possibility that two particles with di erent spins share similar masses. In this paper, we propose a method to probe this kind of mass degeneracy of particles with di erent spins. We use the cascade decay B⁺→X(3872)K⁺, X(3872)→D⁺D^- to illustrate our method. It can be seen that the possible mass degeneracy of X(3872) can lead to interesting behavior in the corresponding cascade decay.
