Electromagnetic properties of (D)over-bar(*)Ξc′, (D)over-bar(*)Λc and (D)over-bars(*)Ξc pentaquarks

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 (D) over bar ((*))Xi(c)', (D) over bar ((*))Lambda(c) and (D) over bar ((*))(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 (D) over bar ((*))Xi(c)', (D) over bar ((*))Lambda(c) and (D) over bar ((*))(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 quarkgluon 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.
