Magnetic dipole moments of $B_{(s)}^{(\ast )}{B}_{(s)}^{(\ast )}$ states

We systematically study the magnetic dipole moments of multiquark states. In this study, the magnetic dipole moments of possible $B^{-}{B}^{\ast -}$, $B^0{B}^{\ast -}$, $B^{-}{B}^{\ast 0}$, $B^0{B}^{\ast 0}$, $B_s^0{B}^{\ast -}$, $B^{-}{B}_s^{\ast 0}$, $B_s^0{B}^{\ast 0}$, $B^0{B}_s^{\ast 0}$ and $B_s^0{B}_s^{\ast 0}$ states are extracted using light-cone sum rules. We explore magnetic dipole moments of these states as molecular picture with spin-parity $J^P=1^{+}$. The magnetic dipole moments of hadrons include useful information on the distributions of internal charge and magnetization, which can be used to understand their geometrical shapes and quark-gluon organization. The results of the present study along with the spectroscopic parameters may help the future theoretical and experimental research on the characteristics of doubly-bottom tetraquark states.
