Abstract
The magnetic and quadrupole moments of the vector and axial-vector mesons containing heavy quark are estimated within the light cone sum rules method. Our predictions on magnetic moments for the vector mesons are compared with the results obtained by other approaches.
Highlights
A study of the electromagnetic properties of hadrons plays a crucial role in understanding their inner structure
The magnetic moments of hadrons are related to their magnetic form factors; more precisely, the magnetic moment is equal to the magnetic form factor at zero momentum square
We see that the values of the magnetic moments of DÃþ and DÃsþ predicted by the light-cone sum rules framework are in good agreement with the other approaches
Summary
A study of the electromagnetic properties of hadrons plays a crucial role in understanding their inner structure. The magnetic moments of heavy mesons have been calculated only in a few works [10,12,13]. In the face of this situation, it is timely to study the magnetic moments of heavy vector and axial-vector mesons. We calculate the magnetic moments of heavy vector and axial-vector mesons within lightcone QCD sum rules (LCSR) [46]. The following section is devoted to the numerical analysis of the sum rules for the multipole moments of heavy vector and axial-vector mesons.
