Exploring the magnetic dipole moments of ${T}_{\mathrm{QQ}\overline{q}\overline{s}}$ and ${T}_{\mathrm{QQ}\overline{s}\overline{s}}$ states in the framework of QCD light-cone sum rules

2023    Azizi, K.; Özdem, U.

Motivated by the recent observation of the tetraquark ${T}_{\mathrm{cc}}^{+}$ , we investigate the magnetic dipole moments of the possible single and double strange partners, ${T}_{\mathrm{QQ}\overline{q}\overline{s}}$ and ${T}_{\mathrm{QQ}\overline{s}\overline{s}}$ , with the spin-parity J P = 1+ by means of the QCD light-cone sum rules. To this end, we model these states as diquark-antidiquark states with different organizations and interpolating currents. The results of magnetic dipole moments obtained using different diquark-antidiquark structures differ from each other, considerably. The magnetic dipole moment is the leading-order response of a bound system to a soft external magnetic field. Therefore, it provides an excellent platform for investigation of the inner structures of hadrons governed by the quark-gluon dynamics of QCD.
