Abstract

To elucidate the internal structure of exotic states is one of the central purposes of hadron physics. Motivated by this, we study the electromagnetic properties of $\bar D^{(*)}\Xi^{\prime}_c$ , $\bar D^{(*)}\Lambda_c$ , $\bar D_s^{(*)}\Lambda_c$ and $\bar D_s^{(*)}\Xi_c$ pentaquarks without strange, with strange and with double strange through QCD light-cone sum rules. We have also evaluated electric quadrupole and magnetic octupole moments of the $\bar D^{*}\Xi^{\prime}_c$ , $\bar D^{*}\Lambda_c$ , $\bar D_s^{*}\Lambda_c$ and $\bar D_s^{*}\Xi_c$ pentaquarks. The magnetic dipole moment is the leading-order response of a bound system to a soft external magnetic field. Thus, it ensures a prominent platform for the examination of the internal organizations of hadrons governed by the quark-gluon dynamics of QCD. We look forward to the present study stimulating the interest of experimentalists in investigating the electromagnetic properties of the hidden-charm pentaquarks.
