Spectrum of ccb¯b¯, bcc¯c¯, and bcb¯b¯ tetraquark states in the dynamical diquark model
The dynamical diquark model assumes that exotic hadrons can be formed from colored diquarks. This model asserts a multiquark exotic state composed of a compact diquark δ and antidiquark δ¯ for a tetraquark interacting through a gluonic field of finite extent.

| description | The dynamical diquark model assumes that exotic hadrons can be formed from colored diquarks. This model asserts a multiquark exotic state composed of a compact diquark δ and antidiquark δ¯ for a tetraquark interacting through a gluonic field of finite extent. Using Born-Oppenheimer (BO) approximation and BO potential calculated numerically on the lattice, we study mass spectra of S-wave ccb¯b¯, bcc¯c¯, and bcb¯b¯ tetraquark systems in the basis of diquark spins. We assume that color-antitriple diquark and color-triplet antidiquark form tetraquark state. The predicted mass spectrum for ground state of ccb¯b¯ is found to be lower then their corresponding two-meson thresholds. This system may be a candidate for bound state. Masses of bcc¯c¯ and bcb¯b¯ tetraquark states are found to be above than the corresponding two-meson thresholds. |
