Abstract

The magnetic moments of the $B_{c}$ $$B_c$$ mesons provide significant insights into their inner structure and geometric shape. Furthermore, a comprehensive understanding of the electromagnetic characteristics of $B_{c}$ $$B_c$$ mesons is essential for advancing our knowledge of confinement and heavy flavor effects. In light of this, we proceed to extract the magnetic moments of the ground-state vector and axial-vector $B_{c}$ $$B_c$$ mesons through the medium of the QCD light-cone sum rules. The magnetic moments of the axial-vector and vector $B_{c}$ $$B_c$$ mesons are found to be $μ_{B_{c}} = - 0.47 \pm 0.07 μ_{N}$ $\mu _{B_c}= -0.47 \pm 0.07~\mu _N$ , and $μ_{B_{c}} = 0.15 \pm 0.02 μ_{N}$ $\mu _{B_c}= 0.15 \pm 0.02~\mu _N$ , respectively. A comparison of our results for the vector $B_{c}$ $$B_c$$ meson with other theoretical predictions has revealed discrepancies between the various predictions, which could prove useful as a complementary tool for interpreting the vector $B_{c}$ $$B_c$$ meson. The current experimental data set is limited to a small number of observed states of beauty-charm mesons. However, theoretical studies can play a valuable role in elucidating their nature and guiding future experimental investigations.
