Exploring electromagnetic characteristics of the vector and axial-vector mesons

The magnetic moments of the mesons provide significant insights into their inner structure and geometric shape. Furthermore, a comprehensive understanding of the electromagnetic characteristics of 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 mesons through the medium of the QCD light-cone sum rules. The magnetic moments of the axial-vector and vector mesons are found to be , and , respectively. A comparison of our results for the vector meson with other theoretical predictions has revealed discrepancies between the various predictions, which could prove useful as a complementary tool for interpreting the vector 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.
