Description
We systematically calculate the mass-spectra of tetraquarks $[cc \bar{b} \bar{b}]$ and $[cb \bar{c} \bar{b}]$ in a non-relativistic diquark-antidiquark model [1,2]. The spin-dependent terms have been incorporated to describe the splitting structure for orbital and radial excitations. We have successfully obtained the experimentally observed $B_{c}^{\pm}$ mesons to fit the model’s parameters which are used to obtain the masses of tetraquarks. The masses of these tetraquarks are found to be in the range of 12.5 GeV- 13.5 GeV, and are compared with the two-meson threshold. The details of the study will be presented in the conference.
