Description
Quarkonium-pair production is a rich observable, providing valuable insights into gluon TMDs, double parton scattering, and, of course, the production mechanism itself. While direct production has been frequently studied, here we investigate the contribution from heavy-quark fragmentation, including, in particular, $D_{Q\to H_1 H_2}$ for the fragmentation of a heavy quark into two quarkonia.
Our analysis is performed within the color glass condensate effective theory, and we present our results for double $J/\psi$ production.
