Description
I will review the status of theory studies of Double Parton Scatterings (DPS) using associated production of quarkonia at colliders. This includes $J/\psi+J/\psi$, $\Upsilon+\Upsilon$, $J/\psi+\Upsilon$, $J/\psi+W$, $J/\psi+Z$, $\Upsilon+D$ and $J/\psi+D$. Where relevant, I will discuss the impact of QCD corrections to Single Parton Scatterings which can affect the extraction of the DPS yield. I will also discuss specific observables related to the quarkonium polarisation and the feed-down pattern which can help verify the dominance of either SPS or DPS contributions in a given kinematical region.
