Magnetic dipole moments of the T-cc(+) and Z(v)(++) tetraquark states

Abstract

Inspired by the observation of the doubly charmed state T-cc and following theoretical studies on its spectroscopic parameters, we investigate its magnetic dipole moment, assigning it the quantum numbers J(P) = 1+, and both the compact diquark-antidiquark and molecular structures in the framework of the light cone QCD. We also calculate the magnetic dipole moment of the theoretically predicted singly charmed state, Z(v)(+)(+), with two units of electric charge and the quantum numbers J(P) = 1(-) in diquark-antidiquark picture. The numerical results are obtained as mu(+)(Tcc-)(Di) = 0.66(-0.23)(+0.34) mu(N), mu(+)(Tcc-Mol) = 0.43(-0.22)(+0.23) mu(N) and mu(++)(Zv) = 3.35(-0.73)(+0.89) mu(N). These results may be checked via other phenomenological approaches. The obtained results may be useful in exact determinations of the natures of these states.
