Abstract:
The magnetic dipole moments of the Z(c)(4020)(+), Z(c)(4200)(+), Z(cs)(4000)(+) and Z(cs)(4220)(+) states are extracted in the framework of the light-cone QCD sum rules. In the calculations, we use the hadronic molecular form of interpolating currents and photon distribution amplitudes to get the magnetic dipole moments of the Z(c)(4020)(+), Z(c)(4200)(+), Z(cs)(4000)(+) and Z(cs)(4220)(+) tetraquark states. The magnetic dipole moments are obtained as mu(zc) = 0.66(-0.25)(+0.27), mu(Zcl) = 1.03(-0.29)(+0.32), mu(Zcs) = 0.73(-0.26)(+0.28) and mu(Zcsl) = 0.77(-0.25)(+0.27) for the Z(c)(4020)(+), Z(c)(4200)(+), Z(cs)(4000)(+) and Z(cs)(4220)(+) states, respectively. We observe that the results obtained for the Z(c)(4020)(+), Z(c)(4200)(+), Z(cs)(4000)(+) and Z(cs)(4220)(+) states are large enough to be measured experimentally. As a by product, we predict the magnetic dipole moments of the neutral Z(cs)(4000) and Z(cs)(4220) states. The results presented here can serve to be helpful knowledge in experimental as well as theoretical studies of the properties of hidden-charm tetraquark states with and without strangeness.
