  "abstract": "The structures in the di-J/psi spectrum seen at the LHC are widely read as fully charmed tetraquarks. As an alternative scenario, the $2^{++}$ production amplitude for a compact $cc\\bar c\\bar c$ source rescattering through ten charmonium-pair channels is presented. The model is completely fixed except for three background parameters and provides a competitive description of the data, with chi-sq/ndf=56/50. Prominent features are driven by J/psi psi(nS) thresholds or threshold enhancement, with no need for exotic hadrons.",
