摘　　要：We systematically study the magnetic dipole moments of multiquark states.In this study,the magnetic dipole moments of possible B^(−)B^(∗−),B^(0)B^(∗−),B^(−)B^(∗0),B^(0)B^(∗0),B_(s)^(0)B^(∗−),B_(−)B_(s)^(∗0),B_(s)^(0)B^(∗0),B^(0)B_(s)^(∗0),and B_(s)^(0)B_(s)^(∗0) states are extracted using light-cone sum rules.We explore the magnetic dipole moments of these states in a molecular picture with spin-parity JP=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 future theoretical and experimental research on the characteristics of doubly-bottom tetraquark states.
