Mass Formulas for Single-Charm Tetraquarks with Fermi-Breit Hyperfine Interaction
In this paper we present the main results of our investigation of the cq (q) over bar(q) over bar single-charm scalar tetraquarks and their SU(3)(F) representations: (15) over bar (S), (3) over bar (S), 6(A) and (3) over bar (A). We use the Fermi-Breit interaction Hamiltonian with SU(3) flavor symmetry breaking to determine the masses of the single-charm tetraquarks. We also discuss mass spectra obtained from meson and baryon mass fits. The mass spectra are very similar to those obtained with Glozman-Riska hyperfine interaction, and they indicate that some of the experimentally detected states may have tetraquark nature.
