Electromagnetic properties of , , And Pentaquarks

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 ${\overline{D}}^{\left(⁎\right)}{\Xi }_{c}^{\prime }$, ${\overline{D}}^{\left(⁎\right)}{\Lambda }_{c}$, ${\overline{D}}_{s}^{\left(⁎\right)}{\Lambda }_{c}$ and ${\overline{D}}_{s}^{\left(⁎\right)}{\Xi }_{c}$ 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 ${\overline{D}}^{⁎}{\Xi }_{c}^{\prime }$, ${\overline{D}}^{⁎}{\Lambda }_{c}$, ${\overline{D}}_{s}^{⁎}{\Lambda }_{c}$ and ${\overline{D}}_{s}^{⁎}{\Xi }_{c}$ 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.
