Mass spectra of hidden bottom tetraquark states

Since the discovery of the X(3872) in 2003 , few botomonium-like XYZ states have been reported in recent years. In present paper, we have computed the masses of hidden bottom tetraquarks (bqb-barq-bar where q ϵ u, d, s) in the diquark-antidiquark framework with the inclusion of spin-spin component of the one gluon exchange interaction. To get binding energy, we have solved Dirac equation using linear potential for two body interactions for tetraquark states. Here we have factorized the four body system is into three subsequent two body systems
