Unveiling the electromagnetic structure and intrinsic dynamics of spin-3/2 hidden-charm pentaquarks: A comprehensive QCD analysis
Year: 2025
Type: article
Abstract: In this study, we investigate the electromagnetic properties specifically, the magnetic dipole, electric quadrupole, and magnetic octupole moments of six hidden-charm pentaquark states: , , , , , and . Employing the framework of QCD light-cone sum rules and utilizing two distinct diquark-diquark-antiquark interpolating currents, we focus on pentaquark configurations with spin-parity quantum numbers . The numerical results demonstrate significant deviations between the magnetic dipole moments predicted using different diquark-diquark-antidiquark structures. These results suggest that multiple pentaquark states with identical quantum numbers and quark constituents may exhibit distinct magnetic dipole moments, depending on their internal quark configurations. The obtained electromagnetic moments, particularly the variations in magnetic dipole moments, may provide insights into the internal structure of hidden-charm pentaquark states.
