1  In a model with three resonances described by interfering relativistic Breit-Wigner functions above background from non-resonant single and double parton scattering and a threshold enhancement.
2  In a model with two resonances, with the ${{\mathit T}_{{{c c {{\overline{\mathit c}}} {{\overline{\mathit c}}}}}}{(6600)}}$ interfering with single parton scattering, and a non-interfering ${{\mathit T}_{{{c c {{\overline{\mathit c}}} {{\overline{\mathit c}}}}}}{(6900)}}$.
